The Thomson MO6 was an 6809E-based computer introduced in France in 1986. It featured 128 KB of RAM, a 40×25 text display, and built-in Microsoft BASIC. The MO6 was available until January 1989.
In Italy it was sold by Olivetti with little aesthetic changes, and named Olivetti Prodest PC128.
The Thomson MO 6 was the successor of the Thomson MO 5. This machine was widely used in French schools. It was compatible with the MO 5 and the other members of its family (TO 7, TO 8, TO 9 and TO 9 plus).
It has two versions of BASIC on ROM, one to be compatible with MO5 and BASIC 128 (both made by Microsoft). Almost all memory (101 KB) was accessible with BASIC thanks to a transparent 16 KB bank switching mechanism. An optional 3.5" floppy disk drive (640 KB) was available.
It had a short life because soon after it was launched, the TO 8 came and challenged to it.

The PDP-11 was an extremely successful and influential family of machines which has spanned over two decades from the early 1970s through the mid 1990s. The first PDP-11 in 1970 cost $10,800 and was DEC's first and only 16 bit computer.
The 11/04 (September 1975) was an implementation of the Unibus pdp-11 architecture, and was essentially a replacement for the 11/05 & 11/10. It was the first pdp-11 to escape without a 'proper' lights & switches front panel, instead it had the glorified 'programmers console' as an option - a hex keypad and an LED display which showed address/data digitally.
It came in two chassis, like the 11/05 & 11/10 - a half-height example, which had the entire Unibus backplane, power supply, front panel - basically the whole computer - sliding into an evil jamming finger-trapping metal sleeve - and a full-height example, basically the same BA11 box as used by the 11/35 and many many other DEC applications. It's very similar to its higher-spec twin, the 11/34. Our model is the half height one.
The PDP 11/04 is a Unibus based 16-bit minicomputer which included the following boards:
M7263 KD11-D 11/04 processor module
M7847-DJ MS11-JP 16-Kword 18-bit RAM
M9312 Bootstrap terminator with 5 empty ROM sockets
M7859 KY11-LB Console interface; programmer's console
M7856 DL11-W RS-232 SLU & realtime clock option
G7273 Bus Grant & Non-processor grant
M8256 RX211 RX02 floppy disk controller
Our model PDP 11/04 BD has a serial number of AB 07040 as well as AB 07033 dated 22nd September 1978
Our machine was very kindly donated by John Millar and is in an unused condition.
The Coolpix 775 is Nikon's first ultra-compact digital camera and offers a 2.14 megapixel resolution and 3x optical zoom in a tiny, easy-to-handle design. The most striking thing about the Coolpix 775 is how small it is, measuring a diminutive 87 x 66 x 44 mm while the design still makes it easy to firmly hold in one hand. The small size of the camera hasn't restricted the available features. To start, the 2.14 megapixel resolution is respectable letting the camera take shots at three sizes 1,600 x 1,200, 1,024 x 768 and 640 x 480. Using the supplied 8 MB compact flash card this only stores eight shots at the top quality setting, though dropping the quality to basic bumps this to 32 shots.
In use the image quality of the Nikon is excellent, thanks to an intelligent white balance feature--no matter what the lighting conditions the camera produces images with excellent colour reproduction. The macro mode is also impressive for such a compact camera. Tie this all in with sharp final images and the results are amongst the best you can expect from a 2.1 megapixel camera.
The 3x optical zoom works quickly and is backed up by a very quick auto focus, though this seemed to be a little noisier than most other cameras. A standard viewfinder is provided but you'll more than likely be using the extremely clear LCD rear display. If you need it a digital zoom is also available and provides up to an additional x2.5 of zoom depending on your selected resolution.
A bonus for the Coolpix is that it comes with a high capacity rechargeable lithium battery and charger. This helps reduce the size of the camera and provides extended battery life. Overall the Coolpix 775 is slightly more expensive than most competing 2 megapixel cameras. However the end results are well worth the money and taking into account the tiny size and supplied charger and battery the price is justified.

The Apple Macintosh IIci was an improvement on the Macintosh IIcx. Sharing the same compact case design with three expansion slots, the IIci improved upon the IIcx's 16 MHz Motorola 68030 CPU and 68882 FPU, replacing them with 25 MHz versions of these chips. The IIci came with either a 40 or an 80 megabyte hard disk. A logic board upgrade was available for IIcx owners. The Quadra 700's case uses the same form factor, and a logic board upgrade was made available for both the IIcx and IIci upon the Quadra's introduction in 1990.
The IIci introduced a lot of technical and architectural enhancements, some of which were important in preparing for System 7 (which was then called the Blue project) and would influence future Macs, though some of them came at the cost of compatibility:
A completely new, 32-bit clean ROM with built-in 32-bit QuickDraw that consists of 2 parts: one part that is the same across all Macs, and another area (called the overpatch area) that is specific to each Mac.
Discontiguous physical memory that are mapped into a contiguous memory area by the MMU. Some of the System 7 VM functions had to be added to the ROM to support getting the physical address of the memory.
An optional 32KB Level 2 cache. The cache card, which fitted into a special slot on the motherboard, was later included in all systems at no charge. Third-party cards offered up to 128KB, but the added RAM yielded little benefit over the base card.[1]
A first for a non-all-in-one Mac — onboard graphics for an external display. This freed one of the system's three NuBus slots. However, because the integrated graphics used the system's RAM for its frame buffer, some users used a NuBus graphics card to reclaim the lost memory. Also, it was popular to install faster memory in the first bank of SIMM slots, as this is the bank used by the video subsystem.
The IIci was one of the most popular and longest lived Mac models of all time. For much of its lifespan, it was the business "workhorse" of the Macintosh line. For a short time in 1989, before the introduction of the 40 MHz Macintosh IIfx, the IIci was the fastest Mac available.

The Comptometer was invented by the American Dorr Eugene Felt and was patented in 1887. Manufactured by the Felt and Tarrant Manufacturing Company of Chicago, the Comptometer was the first truly practical and commercially successful adding machine, with the first serious manufacture and sales occurring in 1888.
They proved very successful and were developed and manufactured in large numbers into the early 1970s.
"Comptometer" eventually became to be used as a generic name for calculators of this type from other manufacturers, though strictly this is wrong.
However, to complicate matters, in 1957 the Felt and Tarrant Manufacturing Company changed its name to Comptometer Corporation. Then in 1960 Comptometer Corporation sold its UK. operation, including the right to the Comptometer name in Britain, to Control Systems Ltd. (the parent of the Bell Punch Company), which merged it with its own company to form Sumlock-Comptometer. Comptometer Corporation then contracted with Control Systems to have all its machines made by Bell Punch in England and shipped back to the U.S.A. This resulted in all Comptometer production ceasing in Chicago in 1961. This resulted in machines from Sumlock being marked with the Comptometer name.
The main manufacturers of Comptometer type machines were:
Felt & Tarrant (later Comptometer Corporation, and Victor Comptometer), the original manufacturer.
Burroughs Adding Machine Co., Detroit, U.S.A.
Bell Punch Co., Uxbridge, England. Sold under the names Plus, Sumlock, and Sumlock Comptometer.
Our model has a serial number of 11696. This model was in production from 1915 to 1920

A 10-decade, decimal Comptometer, electrically driven, with storage (memory).
Model number 912/VZ/S/933.896.
346 x 324 mm x 200 mm (13.5" x 12.75" x 8").
Made in Great Britain by Bell Punch Company Ltd.
Bell Punch acquired the right to use the name "Comptometer" from the U.S. Comptometer Corporation in 1960.
This machine has the standard full keyboard with 12 decades of keys (1 to 9). As usual on Comptometers, pressing a key adds that number to the accumulator register, as shown in the lower row of windows, here showing 12300000.
Pressing the + side of the rocker switch on the right adds the contents of the accumulator register to the storage register (memory) along the top, here showing 24600000. Pressing the "-" side of the rocker switch subtracts the accumulator contents from the storage register.
The clearing switch at lower right can individually clear the accumulator or the storage registers.

This "OREL BK-08" is a soviet clone of famous ZX Spectrum in very rare condition: it has been NEVER opened (factory sealed), never used, full original set, full description, original packaging, OTK (passed factory quality control) marking. I have some quantity, so you can become lucky owner of this vintage NOS computer :)
From a Google translation from the Russian
Original Site: http://witchcraft.org.ua/mnuspeccy/15-orelbk08
General Features
The central processor: UA880A (analog Z80A production GDR) or Z80A, with a frequency of 3.5 MHz. RAM 64 MB implemented in 8 chips KR565RU5V type.
Interfaces:
RGB video output for connecting to a TV, the appropriate GOST 24838-47;
input / output for domestic cassette recorder, used as standard in long-term memory as a device;
two connectors for joysticks like Sinlcair / Kempston;
Connector bus system.
Architecture Features
Shadow RAM
Address space CPU 0-3FFFH using software available registers can be displayed as a ROM, and on the addresses of RAM. The design fee includes the installation of two chipset ROM capacity of 16 KB each, but in practice only used one of them. Ability to select the source for a data read operation, while the recording is always done in RAM. This
organization allows, on the one hand, to organize the loading of data
into shadow RAM means BASIC-built system, but on the other hand, the
contents of the shadow RAM may be affected by programs that do not take
account of its presence. The data in the shadow RAM is not lost after a hard reset button RESET.
Extended Keyboard
Keyboard BC - button, Reed, 67-key. Alphanumeric keypad zone coincides with the standard AT-keyboard set up the modifier keys. Pickup alphabetic keys - standard (QWERTY and QWERTY). Switching of layouts using special access keys RUS and P / A. Poll additional keys through the unused bits in the standard model keyboard port. The
total number of software available keys - 56, other combinations of
hardware emulates pressing Caps-Shift + and are designed to control the
cursor and edit mode.
NMI Button
NMI processor can be initiated by the user by pressing the NMI, BC located on the body. This
possibility, combined with the placement of the shadow RAM debug
monitor is very useful in the development of programs in assembly
language or machine code.
Other circuit design features
Wait
states when accessing RAM available, which improves the system
performance compared to the original ZX Spectrum or its clones such as
the "Leningrad". RAM
regeneration scheme does not depend on the contents of the register I
processor, eliminating the known defect of the original model - the
destruction of the image when recording in the register values
40H-7FH.
Accurate decoding of input-output ports (8 lines of address) favors the development of additional devices.
Request
line INT automatically removed by signal interrupt confirmation, thus
preventing problems with the duration of the query generation.
Number of clock cycles between interrupts is the same as the original ZX Spectrum - 69888.
Address signals to the keyboard output via K155LP9 buffers and not through the diodes, as on many other options ZX Spectrum. This will eliminate any interferences in the system bus from the keyboard.
Signals generated video controller running ROM (chip and K155RE3 K556RT4). Synchronization exactly matches the original ZX Spectrum.
BC is powered DC 24V (AC rectifier supplied). The body is placed BC pulse voltage generating primary supply voltage of +5 V and extra - +12 V. BC is not very sensitive to disturbance, occurring in the electric system, for example, when you turn on the refrigerator. The
load capacity of the stabilizer on the +12 V is very small, but
sufficient to supply the chip KR1818VG93, which was placed in the drive
controller.
Basic software
The
package includes a set of basic BC Software: BASIC interpreter in ROM
and a tape cassette with programs tst, MZ80 and RECLAMA.
Basic System
Flash ROM contains the original version of the ROM ZX Spectrum, adapted to the advanced features of the IC. When loading the message "Basic System ver. 2.0."
Features:
Russification: the 7-bit encoding KOI-7 with a manual change output control codes. Modified ROM routines character input from the keyboard and display. Russian CG character tables are located in the upper address ROM, not involved in the original.
Implemented
traditional ZX Spectrum input function words BASIC language press of a
key, but the arrangement of the words on the keyboard is different from
the original.
Handler
NMI: instead of the default handler implements its activating shadow
RAM, which causes an implicit transfer of control to code located in
RAM.
Known errors corrected the original ROM were not. At
the same time, the differences between BC architecture required to fix
some other problems that were not apparent in the original architecture,
but could cause partial corruption of data in the shadow RAM.
Monitor MZ80
Small
operating system designed for MZ80 run and debug programs in machine
code and provides the following functions: control of the system
input-output, load programs, launch programs, generate and copy the
files (programs), debugging, service capabilities. [2]
The monitor is placed in the shadow RAM and activated by the user by pressing the NMI.
MZ80 opportunities as the debugger is not very diverse. For example, it lacks features such as disassembling the contents of memory or a step by step program execution.
Incorrect
work with the contents of register R processor and features return to
the interrupted program does not guarantee recovery after an NMI.
Program tst
The
program is designed to test the functioning of the main nodes BC:
keyboard, control signal generator of color and brightness, sound
generator, generator control signals color border, RAM and ROM, input
and output signals of a cassette. [3]
Program RECLAMA
Demo implemented on Laser BASIC.
Compatibility
BC provides only partial compatibility with the original. The
main source of problems is the change in the contents of the top
addresses of the ROM, which causes malfunction of programs (eg games
Bomb Jack), using the ROM as the source address of an interrupt handler
mode IM2.

Mavica was a brand of Sony cameras which used removable disks as the main recording media. In August, 1981, Sony announced the Sony Mavica (Magnetic Video Camera) electronic still camera, the first commercial electronic still camera. which was not a digital camera,
The Sony Mavica MVC-FD85 digital camera features a 1.3-megapixel CCD for 1,280 x 960 resolution images. The camera also includes an MPEG movie mode and audio annotation for your pictures. The lens has a 3x optical and 2x digital zoom, plus an automatic macro mode for easy photographing of close-up items. The four-mode automatic flash features red-eye reduction and night-synch modes. The camera's built-in zoom, trim, and resize functions encourage manipulation of the images before they're viewed on your computer. Instead of using a traditional optical viewfinder, users compose images by viewing the 2.5-inch color LCD monitor on the back of the camera. This monitor also indicates remaining shooting time in minutes, a well as indicators for flash, focus, and other functions.
Like most of the other cameras in the Mavica line, the MVC-FD85 uses floppy disks to store photos. At maximum image quality, five images fit on one floppy. At the other end of the spectrum is the e-mail setting, which captures 80 images at 320 x 240 resolution on a single disk. To address concerns about the limited number of photos that can be stored on a low-capacity floppy disk, Sony has devised a high-capacity solution. The camera will accept the MSAC-FD2M Floppy Adapter, a device that looks like a floppy disk. Sony's Memory Stick (available in capacities up to 64 MB) slides into the adapter, and the adapter slides into the camera's floppy drive, essentially giving you a 64 MB floppy disk
The camera has a serial number of 34938 and is complete with a soft case and was kindly donated by Jenny Reeves, it was used in with primary school teachers and pupils.

The Tatung Einstein was released in 1984 costing about £500.
It uses a 3" disk drive (the same used by Sinclair and Amstrad) but I have read somewhere that with a bit of 'handy andying' you can fit a standard 720k 3.5" floppy drive quite easily.
Is it me or does this machine have quite a lot of physical similarities to the Acorn BBC computer? I never had one of these machines but did have a beeb for a long time, and when I took the Einstein out of the box there were several similarities that hit me :
- Similar keyboard action
- Similar expansion connectors
- Similar power supply
- Similar moulded mains plug
- Similar plastic strip above the functions keys
... but technically the machines are very different - The BBC computer being 6502 based and the Einstein being Z80 based for a start!
I've done quite a bit of looking round the web and can't find any other references to these similarities except to say that they are both British computers.
Unusually, the machine boots up into MOS (Machine Operating System) and you need to load a high level language like BBC Basic to use it. Yes, the machine was (I think) supplied with BBC Basic - a strange coincidence bearing in mind the similarities to the beeb ...
The fact that it booted into MOS made it ideal for hardcore programmers to write software and it was apparently on this machine that copy protection systems were developed for other computers due to the fact that you could program the disk controller chip directly.

This computer was assembled by a retired engineer more than 40 years ago has been saved from a skip and donated to a computer museum.
Fred Faulkner, 89, is planning to move nearer family in Stilton this summer and had been clearing out some of the items stored in his bungalow at Mellis Close, Haverhill. He saw an article in the News about the Centre for Computing History moving from Haverhill to Cambridge and contacted the paper to see if they would like his computer.
Jason Fitzpatrick, the centre’s director, said: "We are delighted that Mr Faulkner has decided to donate this key vintage computer - the Transam-Triton- to the Centre. Having survived 40 years, since its construction from a kit back in the 70s, Mr Faulkner’s computer will be preserved for posterity in its new home.”
Widower Fred, will be 90 in May, but still makes clocks in a workshop at his home. He said: "It would definitely have gone in the skip if I had not seen the article in the paper. They came along and collected it and seemed very pleased with it. I ran my own engineering company and wanted something to control the machines and that is how I got into computers. I still make my own clocks. I think if you have something you enjoy doing, you get your head down, and the times goes quickly.”
The Datacard 4000 was used to store messages, names, phone numbers, addresses, meetings and schedules. Plus, up to 25 alarms, 4 function calculator duel clock and calendar
Total memory 4K characters
Power: One Lithium CR2025 battery
It is almost the same size as a credit card and was sold by the 'Innovation's company around 1986/7

This was the final BBC model, it squeezed every last bit of memory out of the 8-bit computer. It is the same as the BBC Model B+ 64K with the addition of a further 64K RAM which is used as sideways RAM and can have ROM images loaded into it. Compared to the BBC Model B, it has:
A redesigned motherboard with the ROM sockets moved to the lefthand side of the board so that they are not covered by the keyboard.
Tthe CPU is changed from a 6502 to a 65C12.
A new OS version 2.00 to support the new features.
The startup messages is changed from "BBC Computer" to "Acorn OS"
A Western Digital 1770 disc controller, instead of the Intel 8271, which supports ADFS as well as DFS
A new DFS version 2.10 to support the WD1770
Additional 32K RAM with 20K for shadow video memory and 12K workspace
Additional 2 ROM expansion sockets
It was launched in 1984 shortly after the BBC Model B+ 64K and was soon replaced by the BBC Master.

The Murray Multiplex System
With the growth of Morse code and hand telegraphy there soon became a need to find faster means of transmission with less manual effort and greater accuracy. Hence the advent of machine telegraphy systems which whilst not using the traditional Morse code signals, generally used a five unit code. This code could basically be created by using a hand operated keyboard, but at much faster speeds than hand operated Morse code. Several earlier systems where invented, but the Murray Multiplex system (or affectionately known as
MUX) was invented by a New Zealander, Donald Murray in 1901. Murray was born in 1866 and died in 1945.
Donald Murray, a New Zealand farmer turned journalist, had invented the Murray multiplex system - another 5-unit code system - which had become popular in India, Australia, New Zealand, Brazil and Russia. Murray made a valuable contribution to telegraphy by rationalising the allocation of the combinations of the 5-unit code to the characters of the alphabet on a frequency-of-occurence basis. His arrangement of the code, in which the most frequently used letters of the alphabet are represented by the smallest number of holes in the tape, has since become standard practice. Murray’s Mulitiplex System and other telegraph patents were acquired by Creed in 1925 and these machines were produced at Croydon for many years. They were "Rolls-Royce" jobs and some of them are in service to this day. A Murray Keyboard Perforator is, in fact, still being used at Telegraph House. In 1926 came the introduction of the Creed Model 6S Automatic Tape Transmitter, the ancestor of the present standard Teleprinter Auto-Transmitter.
A typical system would consist basically of four keyboards, four transmitters, four printers and one distributor at each end of the line. It is an automatic system worked on the duplex system providing up to four duplex arms giving a set of eight channels over a single circuit. Synchronised distributors divide the line time between several operators. Each channel on the Australian system
was designated W X Y and Z
The keyboard (QWERTY layout) mounted on metal base plate with relays and lamp is shown in the picture. The paper tape reel and document holder would have been mounted behind, often with a wooden cover the rear section. It would have been similar to the picture which was taken from http://www.telemuseum.org/teleprinters.html
Facit (Facit AB) was an industrial corporation and manufacturer of office products. It was based in Åtvidaberg, Sweden, and founded in 1922 as AB Åtvidabergs Industrier. Facit AB, a manufacturer of mechanical calculators, was incorporated into the corporation the same year. In 1932, the first ten-digit calculator was manufactured by Åtvidaberg Industries, it was named FACIT and became a great success.
The first of the Facit "inverted" pinwheel calculators was the Model T from 1932. The Model TK is essentially the same machine with a number of mechanical improvements. Although model numbers and exterior styling changed frequently, this basic ten-key mechanism continued in production with only minor changes for almost 40 years, from the mid-1930s into the 1970s. Our calculator is believed to be from the model TK range
This Facit Model has four rules, reversed pinwheel, keyboard type mechanical calculator with a 9 digit keyboard, an 8 digit revolution register and a 13 digit accumulator register. It also has a sliding quotient that dispenses with the need to fill out with zeroes when dividing .

Burroughs Adding Machine Company, 6071 Second Av., Detroit, Michigan, U.S.A.
In 1886 the American Arithmometer Company was founded in St. Louis to manufacture the mechanical add-listing machine invented by William Seward Burroughs. These precision machines were very successful, and in 1904 the company moved to larger premises in Detroit. The following year the name was changed to Burroughs Adding Machine Company.
Other manufacturing plants included those at Nottingham, England (1898); Strathleven, Scotland (1953); and Villiers-Ecalles, Normandy, France (1959). In 1986 Burroughs Corporation and Sperry Corporation merged to form Unisys Corporation.

Compaq iPAQ 3630 Pocket PC
iPAQ presently refers to a Pocket PC and personal digital assistant first unveiled by Compaq in April 2000; the name was borrowed from Compaq's earlier iPAQ Desktop Personal Computers. Since Hewlett-Packard's acquisition of Compaq, the product has been marketed by HP. The devices use a Windows Mobile interface. In addition to this, there are several Linux distributions that will also operate on some of these devices. Earlier, units were modular. "Sleeve" accessories, technically called jackets, which slide around the unit and add functionality such as a card reader, wireless networking, GPS, and even extra batteries were used. Current iPAQs have most of these features integrated into the base device itself.

The Burroughs Corporation was a major American manufacturer of business equipment. The company was founded in 1886 as the American Arithmometer Company and after the 1986 merger with Sperry Univac was renamed as Unisys. The company's history paralleled many of the major developments in computing. At its start it produced mechanical adding machines, and later moved into programmable ledgers and then computers. And while it was one of the largest producers of mainframe computers in the world, Burroughs also produced related equipment as well, including typewriters and printers.
The main target market of the B26 was the banking sector for use in their branches.
They were mostly used in "clustered "configurations: one unit was used as
master unit and several other units (without hard disk) were connected as
slave units. The master unit was handling the file system and the data
communications for the slave units. In Europe a number of large banks had
several thousands of those machines. Air France was also a large customer.
It was also used in the commercial world, but to a lesser extend because of
a lack of packaged application software.
The main mistake first Burroughs then Unisys made was to tie the sale of
CTOS to the sale of proprietary hardware which limited its market. CTOS was
a real and very reliable operating system light years ahead of windows.
We have two B26 machines with the following serial num,bers 319202248 and 318874849. The Buurroughs part number is 3626 0024. These were very kindly donated by Christopher B Clemson
Dolch Computer Systems, Inc. has been around since 1987, offering rugged portable computers and flat-panel displays. Most of their products are geared towards the test and measurement markets and all are virtually bullet-proof.
The FieldPAC is actually much bigger than the picture implies. It is essentially an attache case made of industrial aluminum that so happens to be an almost infinitely expandable portable computer inside. The whole thing weighs a full 17 pounds, but that's because the FieldPAC has a full 14.1-inch display, expansion up to four slots and five drives. Basically, Dolch built an entire desktop computer into that aluminum case, allowing mobile personnel to take desktop power almost anywhere. A "BatteryPAC" option even provides up to six hours of power.

A pocket calculator, which is pretty unusual for normal peoples' usage, is the model "Programmer" from Texas Instruments: This calculator, which appeared on the market in 1977 and which was produced several years, is only capable of the four standard calculations, but is also able to calculate in the hexadecimal and octal number system. And with a few hints, you can also work with binary numbers.
The TI Programmer is capable of doing mathmatics not only on the base-10 system like our natural life but on base-8 and base-16, too. Long before SW-engineeres got nice languages like JAVA or C++ they were used to program the microcontrollers in their native assembler languages. The only things such a microcontroller is executing are simple instructions to manipulate data. With the TI Programmer you could simulate these operations, e.g. AND, OR, XOR and SHIFT's in the dataformat of modern microcontrollers (hex or base-16) or oldfashioned minicomputers (octal or base-8).
Hexadecimal. Octal. Decimal. Performs fast, accurate conversions and calculations in any of these number bases. Enter a number in base 8, 10 or 16. TI Programmer can quickly convert to either of the other bases. Rapidly handle arithmetic computations in all three bases. Ideal for use with any size computer. TI Programmer uses integer "two’s complement" arithmetic in hexadecimal and octal bases. Three key memory lets you store, recall, or sum to memory contents. Decimal base features signed floating point arithmetic for convenience in day-to-day math. Can multiply the effectiveness of anyone in computer programming.
Those calculators were't suitable for normal households, but were mainly used by software developers and computer programmers, which had to calculate bit by bit because of the power-less computers with very tiny memories that time.

Compared with other buggy designs, Trekker's makers concentrated on speed of roaming by swapping the usual stepper motors for dual, geared induction motors to help it get around.
As well as a pen slot, Trekker boasted obstacle sensing via 'bump sensors' that looked like an insect's feelers, an LDR light sensor, white line follower, beeper and nose mounted reed switch for magnet detection. It also looked racier than most of its contemporaries with its shape owing more to radio controlled cars than turtles or robots.
Its brain is a BBC Micro Computer which is attached by a long ribbonm cable. The cost in 1985 was £139.95

An acoustic coupler is an interface device for coupling electrical signals by acoustical means — usually into and out of a telephone instrument. The link is achieved through converting electric signals from the phone line to sound and reconvert sound to electric signals needed for the end terminal, such as a teletypewriter, and back, rather than through direct electrical connection.
Acoustic couplers were sensitive to external noise and depended on the widespread standardisation of the dimensions of telephone handsets. Direct electrical connections to telephone networks, once they were made legal, rapidly became the preferred method of attaching modems, and the use of acoustic couplers dwindled. Acoustic couplers are still used by people travelling in areas of the world where electrical connection to the telephone network is illegal or impractical.[5] Many models of TDDs (Telecommunications Device for the Deaf) still have a built-in acoustic coupler, which allow more universal use with pay phones and for 911 calls by deaf people.
An acoustic coupler is prominently shown early in the 1983 film "WarGames", when character David Lightman (depicted by actor Matthew Broderick) places a telephone handset into the cradle of a film prop acoustic modem to accentuate the act of using telephone lines for interconnection to the developing computer networks of the period, in this case, a military command computer.
This acoustic coupler is a Moore Reed Acoustic Coupler type T.C. 301/m with a serial number of 06213. Unfortunately the pictures do not show the inside of the coupler box as the foam packing is perished at the moment but it does have a lovely varnished purpose made wooden case.

Mavica was a brand of Sony cameras which used removable disks as the main recording media. In August, 1981, Sony announced the Sony Mavica (Magnetic Video Camera) electronic still camera, the first commercial electronic still camera.
Sony brought easy digital photography to the masses when it introduced the Mavica--a digital camera that stored digital pictures on standard floppy discs. This updated version boasts a 2-megapixel sensor and a Memory Stick slot, plus the charm and simplicity that made the original a hit.
The FD200's 2-megapixel sensor captures enough detail for sharp prints at sizes up to 8 by 10 inches. For the typical family photographer, 2 megapixels is a great balance between price and performance. If you want a camera with even more resolution, forget about using low-capacity floppy discs and step up to a CD-recording model instead--try Sony's MVC-CD300 or MVC-CD400.
The autofocus lens features both a 3x optical zoom and a 2x digital zoom. Remember, however, that digital zoom tends to reduce the sharpness and detail of your image, so it's a good idea to use it sparingly.
To save space, there's no traditional optical viewfinder to look through. Instead, to compose your images or review shots you've already taken, the FD200 uses a big 2.5-inch color display. The advantage to using the LCD to frame your shots is that the screen lets you see exactly the picture you'll capture. The disadvantage is that you can't turn off the screen and just use the optical viewfinder to extend battery life. Fortunately, the included rechargeable battery holds a relatively good charge. Considering the internal floppy drive and nonretracting 3x zoom lens, the Mavica is reasonably compact at 5.6 by 4.1 by 3.1 inches, though it weighs in at a hefty 19 ounces.

Our model MVC-FD200 with a serial number of 871241 was kindly donated by Andrew Borkett from the Faculty of Education in Cambridge University.
One of the earliest "programmable computers” that was made available to the general public. It is a 'spiel- und lerncomputer', a 'play and learn computer', an educational tool for the youth and adults alike to get familiar with the wonderful new world of 'automated computing'.
This machine was first sold in 1969 (the preface of the manual is signed 'July, 1969', the same month as the first moonlanding) by a company called 'Piko'. Piko (which stands for Pionier Konstruktion) was a 'Volkseigener Betrieb', a 'company owned by the people' (read: 'state owned') that came into existence in 1948. Actually, its existence was ordered at the time by the Soviet military government because all manufacturers of model trains were in West Germany, and of course the workers of the socialist paradise needed model trains! Apart from trains, Piko specialized in electro-mechanical toys. Today, the company still exists, and is one of the leading brands in model trains.
The East German Piko Dat learning computer was introduced in 1969.
You connect wires to turn them into 'logic gates', you change the connections with 10 plastic drawbars, on the other side there are 13 small lights that are turned on and off.
The MEGA series was intended to be "professional" versions of the 520 and 1040 ST lines. Still running a 68000 8 MHz processor, the MEGA computers could also be connected to a high quality laser printer that was a direct competitor to Apple's LaserWriter (at a significantly lower price). This led to the Atari slogan "Power Without the Price". The machine, like other ST's, could be connected to a color or monochrome monitor and had a matching hard drive unit.
The machine was enhanced by it's use of a battery backed clocked, a Blitter coprocessor which assisted mainly in speeding up graphics and a CPU expansion port. Inside it contains a 720k floppy drive and 2mb of RAM.
the Microcomputer Kit 14 (MK 14) was Sinclair's (at that time called "Science of Cambridge”) first computer. Based on the National Semiconductor SC/MP processor, the MK 14's capabilities were minimal by today's standards - modern digital watches are considerably more powerful!
Despite the MK 14's severe limitations, it was one of the most important British computers ever produced. Its success in finding a previously untapped market was not lost on either Sinclair or his employees, notably Chris Curry, soon to break away and establish Acorn. Without the MK 14, there probably would never have been a ZX81, Spectrum, BBC Micro or Archimedes, and the British computer scene would have been very different.
The MK14 was a computer kit sold by Science of Cambridge of the United Kingdom, first introduced in 1977 for UK£39.95. The MK14 eventually sold over 50,000 units. It used a National Semiconductor SC/MP CPU (INS8060), 256 bytes of random access memory (RAM) which was directly expandable to 640 bytes on board and 2170 bytes total. It used an 8 or 9 red light-emitting diode (LED) seven segment display, there was also optional VDU supporting 32×16 text or 64×64 graphics. Input and output was a 20 key keyboard and reset switch, with an optional 128 bytes of RAM and 16 I/O lines available by adding an INS8154N RAM/IO chip. Cassette-based and PROM storage were optional extras, a sound card was not included but a design for one was provided.

The Psion Organiser was the brand name of a range of pocket computer developed by the British company Psion in the 1980s. The Organiser I (launched in 1984) and Organiser II (launched in 1986) had a characteristic hard plastic sliding cover protecting a 6x6 keyboard with letters arranged alphabetically.
The Psion Organiser I model, launched in 1984 was the "World's First Practical Pocket Computer"[2]. Based on an 8-bit Hitachi 6301-family processor, running at 0.9MHz, with 4kB of ROM and 2kB of static RAM, and had a single-row monochrome LCD screen. The size in mm with the case closed is 142 x 78 x 29.3, and the weight is 225 grams.
The machine provided a simple flat-file database, calculator and clock, and had no operating system. The Organiser I supported removable storage write-once devices which used EPROM storage. The machine could host two of these so-called DATAPAKs (or simply PAKs), to which it could write data but which needed to be removed from the machine and erased by being exposed to ultraviolet light before they could be re-used. As Psion had patented the use of EPROMS as storage device it was impossible for other device manufacturers to copy this innovative approach to mobile storage.
Software supplied on DATAPAK included a crude programming language called POPL, in which end-users could write their own programs. Software DATAPAKs titled Science, Maths and Finance contained the POPL programming language editor, interpreter and runtime and extended the built-in calculator by adding named functions. These DATAPAKs also contained different sets of application programs written in the POPL language.
Our Psion 1 is in very good working order and it is compleyte with the hard case and the Utility and 8K datapacks. We are very grateful to Glenn Oliver who kindly donated our Psion

The Palm Vx was a personal digital assistant made by the Palm Computing division of 3Com. It benefited from the sleek design and low weight of its predecessor, the Palm V, while increasing the available storage to 8 MB. At 114 grams, it was one of the lightest models ever offered by Palm. Retail price at launch was US$299.
Soon after the device's release, Palm Computing was spun off to form Palm, Inc.. The Palm Vx was the first Palm device to be released without "3Com" branding.
The Vx is based on the Palm V design, with the primary difference between the two being the Vx' 8 megabytes of RAM compared to the V's 2 megabytes. This was one of the last palm models not to include a memory slot. It was also one of the first to feature interaction with email, AvantGo, and other online programs.
The Vx is powered by a Motorola Dragonball processor operating at 20 MHz. It was originally equipped with Palm OS 3.3, but later models came with Palm OS 3.5. An upgrade to Palm OS 4.1 was formerly offered for sale on the Palm Website but is no longer available.
The device has a built in rechargeable battery (not replaceable unless the unit is disassembled), and a button on the top of the screen that permitted access to a contrast menu. It also includes an illumination feature, which causes the screen to be backlit by a green glow. However, the default backlight behaviour was inverted so that the text glowed while the background remained dark. This had the unfortunate side effect of making backlit pictures appear as negative images and made the display hard to read if the ambient lighting was at the same level as the backlight. The screen is very crisp and clear in bright sunlight and total darkness.
TDK Blue 5 systems connects the Vx without the cable. Simply connect blue5 to your PalmV or Vx, and you can communicate via Bluetooth to other Bluetooth-enabled devices like mobile phones, PC Cards and USB adaptors. Connect your Palm to a mobile phone with blue5 and you're connected - via GSM for high speed GPRS or HSCSD connections - to the Internet. Powered by the Palm battery, software running on the Palm enables it to control almost all the functions of a mobile phone over the Bluetooth link, which means you can access the full power of Internet-based information services from anywhere, at any time.

The Macintosh Performa series is Apple Computer's consumer product family of Apple Macintosh personal computers sold through department stores and mass-market retailers from 1992 until 1997, when it was superseded by the Power Macintosh 5x00 series. The Performa series was not a new line of computers, but simply renamed models from Apple's regular line of computers — such as Quadra, Centris, LC, and Power Macintosh — sold by authorized Apple resellers. The initial series of models consisted of the Performa 200, based on the Macintosh Classic II, the Performa 400, based on the Macintosh LC II, and the Performa 600, based on the Macintosh IIvx.

Our Linus Write Top Peripheral I has a serial number of 004 and was very kindly donated by John Mawhood
The Linus Write-Top lets you write directly on the screen with the included stylus. It is not a touch screen, it is a "resistive type touch screen in which a voltage is applied to the screen edges, and a stylus detects the voltage at the touched location." This allows for very high resolution and repeatable stylus tracking.
Using an advanced symbol-recognition algorithm, the Linus ("of or about lines") converts your scrawls into perfect text at a rate of about 5 characters per second. It recognizes uppercase, lowercase, numbers, symbols - up to 75 total.
The Write-Top is IBM PC-compatible, with standard serial, printer, external 5 1/4-inch floppy ("D:" drive) ports.
There's also a standard keyboard port so it can be used for word processing or other uses.
The optional internal modem allows transfer of data to remote systems over the telephone line.
An external floppy drive can be attached for local data storage and transfer. The internal 3.5-inch floppy is always available
"What a relief! No more typing, typos or memorizing combinations of keystrokes. Now there's the LINUS wrilc-top: a compact, easy-to-use system that replaces the keyboard and typing with the stylus (pen) and the notepad—tools you already know how to use effectively.
The LINUS writc-lop reads your handwriting and converts it into typewritten (ASCII) formal,
Tasks that were once cumbersome and time consuming can be transformed into streamlined, automated operations. The LINUS write-top in turn allows you to do your job that much better. Just write your comments, complete forms, or even draw with the stylus — it's that simple to use.
While it is easy to use, your LINUS is a powerful tool. Most important, like paper, your LINUS is portable. Whether you use commercial software or specially-developed stylus-based application software, your LINUS is capable of performing an enormous variety of tasks."

The IMSAI 8080 was an early microcomputer released in late 1975, initially based on the Intel 8080 processor (and later on the 8085 processor).
It was a clone of the MITS Altair 8800 computer using the same S-100 bus and is commonly considered to be the first "clone" computer.
The IMSAI 8080 computer ran a highly modified version of the CP/M operating system called IMDOS and was developed, manufactured and sold by IMS Associates, Inc. (later renamed IMSAI Manufacturing Corp).
There were between 17,000 and 20,000 IMSAI 8080 computers produced from 1975 until 1978.
The IMSAI 8080 will be recognised by fans of the 80's blockbuster film 'War Games' as it was the computer used by the main character to hack the US military computer 'WOPR'.
QuickShot was a line of joysticks and other input devices produced by Spectravideo for video game machines including Atari, Commodore, MSX, Amiga, Nintendo and Sega.
SpectraVision was founded in 1981 by Harry Fox and Oscar Jutzeler as a distributor of computer games, contracting external developers to write the software. Their main products were gaming cartridges for the Atari 2600 VCS, Colecovision and Commodore VIC-20.
The world's first ergonomic joystick, the QuickShot, was developed and patented by Harry Fox and Peter Law in 1982 (U.S. Patent D271220). Relatively famous was its Quickshot Maverick joystick, compatible with multiple consoles and home computers. In the late 1990s they expanded their line of products to PC joysticks and mouse. During the 1990s the company marketed a handheld game console called the Quickshot Supervision, a UK version of an Asian console designed to compete with the Nintendo Game Boy.
It has Standard Atari format compatible with most 8-bit formats, like Atari VCS / 2600, Commodore 64 / Amiga, Atari ST, Spectrum with an interface and many more.
Year: 1983
Manufacturer: Spectravideo (UK)
Original price: £16.95

The Quadram Quadboard was an 8-bit ISA RAM expansion card used in XT class machines. The card also featured games (joystick) and printer ports, and a real-time clock (backed by a Varta 2/100 DKO 2.4V PCB mounted battery).
QUADBOARD
Quadram now gives IBM PC and XT users greater flexibility and more expansion possibilities with Quadboard. Regardless of whether the IBM Personal Computer is being used at home or at the office, Quadboard can solve a major problem many users have. Because Quadram has taken 9 of the most-needed IBM PC functions and combined them all onto one board requiring just one expansion slot. This leaves the IBM with the rest of its slots free for future expansion.
Quadboard contains a serial RS-232C communications port, a Centronics compatible parallel printer port, up to 384K of RAM, chronograph (real-time clock/calendar), game port, QuadRAM Drive (RAM Disk) software, MasterSpool (software print spooler), MasterCache (disk caching), and Qswap (a line printer swap program).
A DIP Switch and jumper pins provided on the Quadboard allow you to program the board for the specific needs of your system.
The parallel and serial ports are functionally identical to IBM's.
The chronograph {extremely accurate clock/calendar) uses a crystal controlled integrated circuit with a life time rechargeable battery.
And the game port is fully IBM-compatible. It can be used with game paddles or joysticks. Complete software instructions and descriptions are included in the "QuadMaster II Operations Manual."
Card Type Multi-I/O card
Maximum Onboard Memory 384KB DRAM
I/O Options Game port, parallel port, serial port

The best feature of the Octopus was its expandability, with its main board providing an expansion slot so that other boards or extra processors can be piggybacked on to it.
Octopus 8-bit microcomputer with a 16-bit processor from LSI. LSI is marketing the Octopus as a flexible machine, suitable for single-users, but capable of expansion as the needs of the company grows. In its minimum configuration, the Octopus is a transportable computer which uses a television set as a screen. This can be expanded to comprise a 16-bit microcomputer with up to 6 terminals, which can be linked to other microcomputers as a local area network. The dual processors in the Octopus are the Intel 8088 and the Zilog Z80B, which will run both 16-bit and 8-bit software. Operating systems are Control Program Monitor (CP/M)-86/80 PLUS, MP/M-86/80, Microsoft disk operating system, concurrent CP/M and the ELSIE System of LSI.
LSI Computers Ltd was a British company from Woking in Surrey.

Compaq Computer Corporation was a company founded in 1982, that developed, sold and supported computers and related products and services. Compaq produced some of the first IBM PC compatible computers, being the first company to legally reverse-engineer IBM Personal Computer. It rose to become the largest supplier of PC systems during the 1990s before being overtaken by Dell in 2001. Struggling in the aftermath of the dot-com bubble bust, Compaq was acquired for US$25 billion by HP in 2002. The Compaq brand remained used by HP for lower-end systems.
On June 28, 1984 Compaq released the Compaq Deskpro, a 16-bit desktop computer using an Intel 8086 microprocessor running at 7.14 MHz. It was considerably faster than an IBM PC and was, like the Compaq Portable, also capable of running IBM software. It was Compaq's first non-portable computer and began the Compaq Deskpro line of computers.
Our model is from Series 3021 with 256VGA.

The SPARCstation, SPARCserver and SPARCcenter product lines were a series of SPARC-based computer workstations and servers in desktop, deskside (pedestal) and rack-based form factor developed and sold by Sun Microsystems
The first SPARCstation was the SPARCstation 1 (also known as the Sun 4/60), introduced in 1989. The series was very popular and introduced the Sun-4c architecture, a variant of the Sun-4 architecture previously introduced in the Sun 4/260. Thanks in part to the delay in the development of more modern processors from Motorola, the SPARCstation series was very successful across the entire industry. The last model bearing the SPARCstation name was the SPARCstation 20. The series was replaced by the Sun Ultra series in 1995.

Alfred from Robot City Technology
The 'Alfred' arm made its first appearance in a series of constructional articles in Everyday Electronics magazine in late 1984. The articles were written by Alfred's creator, Alan Green. (It seems the Alfred name was a shortened version of 'Alan's friend' - a name Alan Green gave to his home built robot to impress his six year old daughter and her school friends.) The Everyday Electronics DIY version, as illustrated on the left, used six model servos and was designed to be controlled by a BBC B. It housed an array of discrete TTL chips to code and decode 8-bit parallel data signals, with much of the processing work done by the Beeb's CPU. A set of parts was available from Robot City Technology Ltd (RCT), which I presume was Alan Green's own company. Prices were around £160 ready built and £120 in kit form.
A slicker, more commercial version of Alfred had been developed by RCT by 1985/86 and is illustrated below. This later Alfred used essentially the same external casing, servos and toothed belt design, but replaced the original electronics with an 'intelligent' motherboard running an 8MHz Z8681 MCU with separate 2K ram chip and 8K eprom. This allowed it to be driven, potentially, by any micro that could handle a bi-directional serial or parallel data stream - as the Z8 has multiple 8-bit data ports and an on-chip UART for serial comms. RCT's mark I board retained a 34-way IDC plug for parallel data transfer. The later mark II version was fitted with a serial interface instead, for compatibility with a wider range of micros. By this point the prices had risen to £200 for a kit and £270 fully assembled.
Our Alfred is in excellent condition and was kindly donated by Mrs N Smith
The T5 has a 416MHz Intel processor, 256 megs of RAM with 215 megs available, a high res + 320 x 480 display that runs in both portrait and landscape orientations, a removable flip cover and an SD slot that supports SDIO. It uses palmOne's new "multiconnector" which replaces their universal connector and supports niceties like audio out. Speaking of audio, the T5 also functions as an MP3 player. Unlike the T3, the T5 doesn't have a voice recorder or vibrating alarms.

"The Tungsten T5 is the successor to the popular Tungsten T3 and is palmOne's flagship "business" PDA. Not that you can't use the T5 for multimedia, but its fast processor, plentiful memory and lack of camera put it in the business class. While the Tungsten T, T2 and T3 featured a unique slider design, the T5 has a slate form factor and doesn't slide.
The T5 has Bluetooth wireless personal area networking, 256 megs of RAM and runs on the fastest processor available in a Palm OS PDA. While it doesn't have WiFi, you can add that on using palmOne's SD WiFi card reviewed here. While many of us were hoping that the T5 would run Palm OS 6 (Cobalt), it runs Palm OS 5.4.5 with several enhancements from palmOne including a file system browser and the ability to mount the T5's 160 meg memory partition as a USB removable drive on your computer. PalmOne told us that they'd been working on the T5 before OS 6 was finalized, and that's why we don't see it on this device."

Econet was Acorn's low-cost local area network system, intended for use by schools and small businesses. Econet is rumoured to be an abbreviation of Economy Network, but Acorn were always careful to stress the Greek root, oikos, meaning "house".
Econet was first introduced for use with the Acorn Atom and Acorn System 2/3/4 computers in 1981. It became popular as a networking system for the BBC Micro and Archimedes computers. The Econet system was eventually supported on all post-Atom Acorn machines except the Electron, the A3010 and the eventually-cancelled Phoebe 2100. The system was supported by Acorn MOS, RISC OS and RISC iX. Acorn received an offer from Commodore International to license the technology, which it refused.
The Acorn Econet Bridge is unique amongst Cheese Wedges as it is the only one which does not connect to a BBC Micro. The Bridge connects into an Econet network as if it were a clock or a station. Its function is to link together two Econet networks.

This is the original Pilot model. It's so old it actually says "U.S. Robotics" on it. It holds half a meg of RAM and has the basic computing power of a Macintosh SE. There's no backlight. Palm became a subsidiary of 3Com when U.S. Robotics was acquired by 3Com. In June 1998, the founders became unhappy at the direction in which 3Com was taking the company, and they left and founded Handspring.
The Pilot 1000 and Pilot 5000 were early Palm PDAs produced by Palm, Inc. (then a subsidiary of U.S. Robotics). It was introduced in March 1996.
The Pilot uses a Motorola 68328 processor at 16 MHz, and had 128 KB (Pilot 1000) or 512 KB (Pilot 5000) built in memory.
The PDA has a plastic case (various colors). Its dimensions are 120x80x18 mm and weight is 160 grams. The Pilot has a 160x160 pixel monochrome LCD tactile panel, with a "Graffiti input zone" presented in the bottom third of the screen. Underneath the screen sits a green on/off button, four applications buttons (Date Book, Address Book, To Do List, and Memo Pad) and two scroll buttons. At left, contrast control. At right top, stylus slot. On the back of the device there is a Memory Slot door, Reset button, battery compartment (held two AAA batteries) and Serial Port (for use with the PalmPilot Cradle).
Memory is kept in a "memory slot" under a plastic cover at the back top of the PDA. A 512 KB ROM chip stores the Palm OS 1.0 and resident applications. RAM is available in 128 KB, 512 KB or 1 MB; with a PalmPilot Professional memory card, up to 2 MB of RAM. Hardware limit is 12 MB of RAM and 4 MB of ROM.
Designed by U.S. Robotics, the diminutive Pilot comes with a powerful suite of pen-based organizer applications and a unique cradle that connects to your PC, making it a snap to keep your data in sync. The more you use it, the more the Pilot becomes a natural extension of your PC. . . .
It measures only 4.7 by 3.2 by 0.7 inches and weighs 5.5 ounces. It slips easily into a shirt pocket and is slim enough to fit comfortably in even small hands. About the only criticism that can be leveled at the hardware configuration is that the desktop connection requires a dedicated serial port—a scarce commodity on some systems.
The Pilot's 3.4-inch monochrome screen is readable in nearly all conditions, except direct sunlight. Although the display feels small, the Pilot's software makes efficient use of the limited screen real estate with a clean, uncluttered interface and a bold, easily readable typeface.
With a footprint slightly smaller than that of a 3.5-inch floppy disk, the cradle holds the Pilot securely and connects it to your PC. To synchronize, simply slip the Pilot into the cradle and press the HotSync button in the lower-right-hand corner. . . . The Pilot is an innovative entry in the world of handheld computing

The PowerBook 500 series (codenamed Blackbird, which it shared with the older Macintosh IIfx) was a range of Apple Macintosh PowerBook portable computers first introduced by Apple Computer with the 540c model on 16 May 1994. The 500 series was the first laptop computer to use a trackpad instead of a trackball as a built-in pointing device and the first to have Ethernet networking built-in.
It was the first PowerBook series to use a Motorola 68LC040 CPU (simultaneous with Duo 280) and be upgradeable to the PowerPC architecture via a swap out CPU daughter card (with the PowerPC and 68040 upgrades for sale), use 9.5" Dual Scan passive color/B&W displays, 16bit stereo sound with stereo speakers, have an expansion bay, PC Card capability, two battery bays (and a ten minute sleep/clock battery, which allowed for main batteries to be swapped out while in sleep mode), full size keyboard with F1-F12 function keys, be able to sleep while connected to an external monitor and have a battery contact cover included on the actual batteries. It included a single serial port which could be to connect to a serial printer or a network via Apple's LocalTalk. In another first, it also included an AAUI port for connecting to non-LocalTalk (usually Ethernet) networks.
The 500 series was discontinued completely with the introduction of the ill-fated PowerBook 5300. The PowerBook 190 was the de facto successor to the 500 and continued the only 68LC040 processor offering as the low-end of the PPC-based PowerBook family.

Dubbed the eMate 300, the device was shipped with a solid dark green casing as opposed to the clear casing of this particlar model. Very few of these see-through eMates were ever produced, making this one a very rare exhibit. Originally designed as a low-cost device for the education market, it also appears to have inspired the design of the clamshell iBook laptops released back in the 90s. Either way a seller listed this eMate 300 for a of $8,499.99 on eBay.
Vintage PROTOTYPE Apple Computer eMate 300 PDA Laptop. Approx. circa 1996-1997. The eMate 300 laptops were originally planned to be made in Green, Clear, Red, Purple, & Orange colors. Only the dark green eMates made it into production. This pre-production prototype has a clear case. There are a few small dark green panels (ie. next to the keyboard, and the port surrounds on the sides) which demonstrate what the standard color eMate. It has prototype designation on the bottom & the FCC did eventually approve the eMate). Alledgedly only six of these clear case prototypes were ever made. After they were no longer needed, they were awarded to those involved with the eMate project. Comes with the eMate Stylus & a standard Apple Newton AC power supply. The computer is in good condition with only light signs of use. It.
The eMate 300 was a personal digital assistant designed, manufactured and sold by Apple Computer to the education market as a low-cost laptop running the Newton operating system. The eMate was introduced March 7, 1997, for US$800 and was discontinued along with the Apple Newton product line and its operating system on February 27, 1998
The eMate 300 featured a 480x320 resolution 16-shade grayscale display with a backlight, a stylus pen, a full-sized keyboard, an infrared port, and standard Macintosh serial/LocalTalk ports. Power came from built-in rechargeable batteries, which lasted up to 28 hours on full charge. In order to achieve its low price, the eMate 300 did not have all the features of the contemporary Newton equivalent, the MessagePad 2000. The eMate used a 25 MHz ARM 710a RISC processor and had less memory than the MessagePad 2000 which used a StrongARM 110 RISC processor and was more expandable.
The eMate 300 featured a green-colored translucent durable case designed for intense use in classrooms. The eMate 300 featured a dark green-colored keyboard similar to that of PowerBooks of the same era. Purple, red, and orange colored eMate prototypes were produced especially for show only and were never put into mass production
The Apple eMate 300, designed for the education market, features a 25 MHz ARM 710a processor, 8 MB of ROM, 3 MB of RAM (1MB of DRAM, 2 MB of Flash Memory for user storage), a PCMCIA slot, IrDA-beaming capabilities, and a Newton InterConnect port for multiple connectivity options, in a translucent aquamarine and black "clamshell" portable case with a 480x320 16-shade grayscale backlit LCD display for use with either a provided stylus or the built-in keyboard. The eMate is the only Newton model to resemble a traditional laptop rather than a handheld, but had the Newton line continued, additional models would have likely followed. Please note that eMate is technically not a 'Mac', as it does not operate the MacOS, and instead uses the NewtonOS (also developed by Apple).
The eMate's unusual design eventually influenced the first iBook series, which also featured durable plastic casing with a handle.

Burroughs was one of the first companies in the U.S. to successfully market the electronic calculator. The first machines were built for Burroughs by Sharp in Japan. These machines, identified as the C3000 line (C3100, C3200, C3300, C3350) were large, used Nixie tubes for the display, and were very expensive.
The early machines were so fast as to amaze everyone who saw them, and at the same time, so slow that when the operator performed a difficult calculation, such as a square root (on the C3350), you could see the tubes flash as the calculation was under way.
Burroughs built many models over the years of production, including a book keeping model with a moving printer. Never a market leader, these machines were very early on the market and were sold to replace the thousands of currently installed mechanical machines in Burroughs accounts.

The Apple Macintosh PowerBook 150 was a laptop personal computer created by Apple Computer which was introduced on July 13, 1994 and released on July 18, 1994. It was the last member of the PowerBook 100 series to use the original case design, the most affordable of the series when introduced, priced between $1450 and $1600, and also the last consumer model. It was 8 MHz faster than its predecessor, the PowerBook 145B. It lacked an ADB port and used a lower quality passive matrix display than other current offerings, both to reduce the price. Like the Duos & PowerBook 100 before it, the 150 only had a single serial printer port, however, a third party adapter was available for use in the optional modem slot.
Though it used the 140 case design, its internals were based on the PowerBook Duo 230 and actually more similar to the features of the PowerBook 190 (which used the PowerBook 5300's case design). Notably, this new logicboard design allowed this 100 series PowerBook to use more than 14 MB RAM for the first time, as well as the first Macintosh ever to use less expensive and larger IDE drives (formatting required a unique software application limiting the selection of compatible drives). It was also the first of the 100 series to include a lithium-ion backup battery to preserve RAM contents when the battery is replaced. This was the last PowerBook model to include a trackball. However, like the 145B it replaced, the 150 could not be used in SCSI Disk Mode, unlike the Duo, 190 and 5300 which had HD Target Mode implemented.
