A W Faber-Castell GmbH has its origins in the pencil making firm founded by Kasper Faber in 1761. They started making slide rules in 1882 and became Faber-Castell after 1906. Besides slide rules they have made a wide range of pencils and other drawing items such as scale rules.
The Rietz name comes from 1902 when MAX RIETZ modified and enhanced the »System Mannheim« with a X-cubic scale and mantissa scale on front and gaps with index lines on the back side: Now the slider could be read on the back side without turning the slider in the slide rule. 1925 he added a reciprocal-X scale and scales for small angles.
The Faber-Castell 57/87 Student Rietz is a ten inch closed frame plastic slide rule dated 3/65. It has a clear plastic case and instructions. Scales are: inK,A{B,C1,C}D,L//{S,ST,T}.
Our slide rule is complete with the original instructions and the clear plastic case. This was very kindly donated by Tony Priest
One of the first successful single board micros was the Ohio Scientifc Superboard II. In 1978, this machine shipped with a 6502 processor, 4K of memory and was expandable to quite respectable 8K. The video system displayed 24 lines of 24 characters on a monochrome composite monitor and a system monitor and 8K Microsoft BASIC was supplied in ROM. All you had to do was add your own case, power supply, display, and a cassette recorder for saving/loading programs. The price? An astoundingly affordable $279. They also offered basically the same system as the Challenger IP with case and power supply for $349, and a fully expanded system with 16K memory and a 5 1/4-inch floppy drive wentfor $1190. OSI sold a considerable number of these machines to hobbyists because the 1P was extremely good value.
Our unit Superboard II model 610 has been enhanced with additional memory board and hard disk interface and was very kindly donated by Michael J Davis from Rochdale who has ownwed the system since new. It has a Control Data CDC 5.25" dual disk drive unit as well as a power supply. This is all in excellent condition and includes all manuals and documentation

The Displayphone was interesting attempt to combine voice and data functionality in one unit. Although we take voice and data integration for granted today, back in 1982 this was a unique, and slightly futuristic concept. The Displayphone combines a telephone with a small computer terminal and a blazingly fast :-) 300 baud modem. The terminal also features a few basic personal productivity applications.
Although it never garnered much success in the telephony market, it did prove to be a hit with movie goers. The high-tech look of this early 80's technology proved to be too much to resist of the producers of sci-fi flicks of the period. I've been told that the Displayphone appeared in a number of movies where it was protrayed as a furturistic video phone - a novel concept for the time, but certainly a function never actually performed by this artifact.
Ourdisplayphone incudes an external power supply unit and was kindly donated by William McDowell.
The model number is NT6K80 AA with a serial number of 003164 and a date of December 1985
The NEC APC Advanced Personal computer (October 1983) is quite a large/heavy machine which was a very reliable business computer. It runs CP/M-86 and MS-DOS. It is one of the very few machines which runs MS-DOS from 8" floppy disks.
The NEC Advanced Personal Computer runs at 5 MHz and has a detachable key-board but apartfrom that it sits in a single cabinet: no disk plinth and separate monitor. The cabinet contains integral, vertically mounted 8" floppy disks and a built in monitor The 8' disks ate breakaways from the normal standard of 51/4" buy repay the user with over 1 Megabyte per drive at double-density, doublet-sided or equally can operate in single-density. IBM 3740 compatible mode. They are fast, but rather noisy.
The single module appearance disguises the fact that the APC comes in significantly different configurations. The basic machine, which starts at $7388, comes with 128K of RAM, a single disk drive, a Centronics and one RS-232 port, sound, and a green screen monitor
Ourunit is the basic monochrome APC with a serial number of 3908266N and was made in Japan

Our IBM Options External V.34Data/Fax Modem model no. MT2834BLK has a serial number of 42-P2055 and was manufactured by MultiTech for IBM and was introduced in 1996. It is complete with power supply, cables and manuals all in the original IBM Options box.
The MultiModem BL Series modem connections can be made on Public Switched Telephone Networks (PSTNs) and/or point-to-point 2-wire and 4-wire leased telephone type circuits. Your modem offers interactive automatic dialing, as well as Command Mode option configuration. You may store up to ten command line/telephone numbers, of up to 60 characters each, in the modem’s nonvolatile memory. The modem pulse or tone dials, and recognizes dial tones and busy signals for reliable call-progress detection. The modem can detect AT&T calling card tones. It is FCC-Registered for connection to telephone networks without any Data Access Arrangements (DAA’s).
The modem also features Callback Security to protect networks from unauthorized use, and to manage phone line costs. By using the modem’s phone number and password directory, a host site can, upon receipt of a call, callback to a remote site at a predetermined number. Remote Configuration permits you to assist users at remote sites, saving you the time and trouble of site visits and preventing misinterpretation of configuration instructions.
The MT2834BL modem meets the proposed Enhanced V.34 ITU standard for data signalling rates as high as 33.6/31.2K bps in full duplex mode. Enhanced V.34 is an extension of V.32/V.32bis/V34 standards, and supports and is compatible with those features, including EIA extended Automode; adaptive line probing; automatic symbol rate and carrier frequency during start-up; and retrain and rate renegotiation (in 2400 bps increments).
The major application for the MT2834BL is in 4-wire leased line networks with the addition of dial backup capability. With this capability, the dial-up feature saves any down time if the leased line fails. Since the MT2834BL operates according to ITU V.34 modulation, it can operate full-duplex over two wires, so that the dial backup mode performs the same throughput as the leased line.
The MT2834BL features ITU V.42 error correction and V.42bis data compression, providing 100% error-free data transmission. V.42 error correction incorporates MNP( Classes 3 and 4, and LAP-M. You may select V.42bis data compression for 4-1 throughput, or MNP Class 5 for 2-1 throughput.)

Advanced Gravis MouseStick for the Amiga/Atari ST
The Advanced Gravis MouseStick is an ST controller that can replace your mouse, joystick or both. It's easy to connect and use, and can be configured for a host of options.
The MouseStick actually consists of two units: the stick itself and the Gravis Mouse Processing Unit (GMPU). The stick is mounted on a wide, stable base with rubber feet, and is connected to the GMPU, which plugs into your joystick or mouse port. There are two fire buttons on the base and one on top of the stick.
You can set the base fire buttons to emulate your right and left mouse buttons, or to emulate your left mouse button and activate the MouseStick editor.
The mouse editor lets you configure the MouseStick and includes a variety of options. Since the GMPU has only a single-line LCD display, however, programming it is slow and somewhat tedious. You can save up to four configurations (three plus the default configuration).
Enter the editor for a true test of your trigger finger; you have to push the designated editor button three times fast and hold it down on the last press. The editor gives you a list of options the most complex of which is RECALL A SETUP Besides letting you recall any one of the four configurations, it lets you set the MouseStick for AUTO CENTERING, VECTORING, COMBINATION or JOYSTICK modes.
AUTO CENTERING gives you direct control over the mouse pointer and returns the pointer to the center of the screen when you release the stick. In VECTORING mode, the pointer position glides across the screen in the direction of your stick handle's movement. COMBINATION mode provides a combination of AUTO CENTERING (when the stick handle is upright) and VECTORING (when it's moved left and right). JOYSTICK mode sets the MouseStick to emulate a standard eight-position joystick.
PROGRAM A BUTTON option allows any of the three buttons on the MouseStick to be set in TURBO FIRE mode. This is handy for some games, although rapid fire attachment for joysticks are sold at most toy store for about five dollars.
Our unit is in the original box with a serial No. of 9005839 and the GMPU with a serialNo. of 9004456 and was kindly donated by Andy Taylor of http://www.retrocomputers.eu/ In July 1991 this cost £69.00 + £1.50 P & P

Sumlock Duolectric Comptometer
Sumlock dual-register comptometer, Model 912, S/N 912/S/Va/510,003B 12 columns (13 digits), Sterling, dual register, electric Dimensions: 13"W x 13"D x 8"H Weight: 29 pounds the Duolectric cost £325 [about US$900] Manufactured: Bell Punch Company, England, 1953 onwards
A 12-column machine for Sterling currency (no farthings), with an electric motor drive and a second "grand total" register at the rear. The Bell Punch Company (BPC) was established in London in 1878, and took its name from its original product - a bus conductor's registering ticket punch. The company expanded into ticket printing and issuing equipment for buses, trams, and cinemas, racecourse betting tickets, and taxi meters. Their activities were generally related to "cash control systems", and were coordinated through a holding company "Control Systems Ltd" from 1927. Both companies established branches in Australia and other Commonwealth countries. In 1936 the company purchased the rights to a small half-keyboard adding machine which was sold as the "PLUS Rapid Adder". Larger full-keyboard versions with Comptometer-style safety mechanisms were marketed under the name "Sumlock". The London Computator Corporation was established in 1940 to handle the calculator business, but the nameplate soon reverted to The Bell Punch Company.
The PLUS and Sumlock machines were very popular in Britain and Commonwealth countries. They continued in production for almost 40 years, until replaced by computers and electronic calculators in the 1970s. In the late 1950s the Bell Punch Company acquired the British rights to the Comptometer name from the ailing Comptometer Corporation (formerly Felt & Tarrant) of Chicago. When Comptometer production ended in 1961, the Bell Punch Company exported re-badged Sumlock machines to America to be sold as new-model Comptometers.
Our machine is in excellent condition and has a model number of 912/S/4a/507.034.A and was very kindly donated by Mrs Pauline A Toghill

Sumlock Sumlomatic 1959
The "Sumlomatic" was the final development of the Bell Punch Company's mechanical calculators. It is based on the motor driven dual-register machine, with the addition of a third register and a control mechanism to perform semi-automatic multiplication. The concept is described in Webb's US Patent 2956741, filed in 1955, but the machine did not reach the market until 1959. A full keyboard Sterling Currency "Comptometer" type machine with a multiplier register. According to an exhibition review in "Office Magazine" for June 1958: "The star on the Sumlock stand is the Sumlomatic. This is a new key-driven calculator with a multiplier register as well as the usual working register and store register. Digits for the multiplier (the lowest-register in the illustration) are set from the keyboard by means of a transfer button (seen on the right) which is also used to transfer digits from the working register to the store register. For repetitive multiplication by the same factor the multiplier register is provided (on its left) with a locking switch. The large key seen to tthe left of the board is the multiplier control. Whilst addition and subtraction can be in £ s. d., multiplying must be in decimals. Division is done by turning to a printed table of reciprocals and then multiplying. In busy commercial offices where several kinds of computation are done, the use of the Sumlomatic will undoubtedly lead to a daily saving of many thousands of key depressions as compared with previous models. This remarkable new model weighs 341b. and costs £330 [about US$900]."
The Bell Punch company did not manufacture any calculators until the 1930s when in 1936 the parent company, Control Systems, acquired the rights to the adding machines of the Comptometer type manufactured by Petters, Limited, of Yeovil, England and sold under the name "Pettometer".Due in part to the use of the old £sd Sterling currency and imperial units of measurement in Britain and the British Commonwealth, Bell Punch manufactured a greater variety of "Comptometer" type calculators than any other company.

Integra Technologies Ltd of Welwyn Garden City UK supplied the Computer-Link Tape Cleaner & Tester.
Although no model number is evident, it appears to be a Computer Link 1022-3. There were three versions of the 1022 and the model 3 was distinguished by the inclusion of an automatic opening door. This information was very kindly supplied by Don Blackburn - Sales Director for for Bow Industries, Inc. - www.bowindustries.com.
As this machine was to handle reel - to reel tapes, we assume that it dates from the late seventies to the early eighties.
Thanks again to Don Blackburn of www.bowindustries.com the following is an extract from a publicity leaflet
MODEL 1022-Fastest Tape Cleaning Time At 2.67 Minutes
• Exclusive Automatic Safety Door assures Operator safety The operator is completely protected against injury from moving parts.
• Automatic Stacking Wheel eliminates damage to tape edges caused by mishandling Assures smooth tape winds to avoid handling and shipping damage to tape edges.
• Physical Defect Scanner detects physical damage on tapes without destroy¬ing data Will find and automatically display errors for the operator; i.e. holes in tape, damaged edges, scal¬loped or folded, nicks, oxide voids, defective splices, scratches, wrinkles or cinches which have damaged the tape. Scanner will find errors in an area of 0.020 inches (.5 mm) or larger and automatically relocate for visual inspection.
• Physical Damage Detection eliminates aborts and reruns due to physical damage on tapes A physical damage detec¬tor with automatic error retrieval enables inspection of tape for physical damage. Models 1022-2 and 3 respond similarly to a certifier by automatically relocating to defective areas for examination or stripping of tape.
• Exclusive LED Damage Location Display allows quick operator analysis of tapes with physical damage LED graph displays error locations for quick analysis of the tape's condition; e.g. retain, or discard.
• Exclusive Illuminated Viewing Station allows operator to inspect the physical damage In addition to automatically relocating on defective areas, an inspection light automatically turns on to further aid in seeing the damage.
• Tape Leader Check eliminates tape load malfunctions Length of tape leader is accurately and auto¬matically measured and displayed to eliminate tape load malfunctions due to short leaders.
• Exclusive Archival Wind assures proper stacking tension for long term storage Archival wind speed is a standard feature designed for long term stable tape storage during prolonged reel retention cycles.
• B.O.T. Check identifies those tapes that can cause costly load malfunctions Model 1022-3 automatically searches for missing or multiple B.O.T. markers and stops for repair.
• Automatic Search saves time in stripping and B.O.T. /E.O.T. replacement When a length of tape is selected by the operator for cutting or examination, the cleaner automatically advances the tape at maximum speed to the desired area.
• Correct Tension Control The Model 1022 provides precise independent con¬trol of the cleaning tension and rewinding tension for tape used through 6250 bpi.

The PowerBook 180 was the first portable Mac with a 4-bit active matrix display. With a 33 MHz CPU and improved screen, it replaced the PB 170 and was in very high demand through its life. Like the PB 160, the 180 has a video out port supporting an external 13" to 16" monitor. With the PB 160, it was the first PowerBook to support more than 8 MB of RAM.
The PB 180 reintroduced SCSI Disk Mode to the PowerBook line, a feature previously found only on the PB 100.
As with all early PowerBooks, when buying used be sure it has all the memory you need (new PB RAM is getting more difficult to locate, especially at reasonable prices).
The PB 180 has a 14 MB memory ceiling, although you can go beyond that by using Virtual Memory (slow and free) or RAM Doubler (faster, not free, and discontinued). Another option is RAM Charger 8.1, which offers better memory management than the Mac OS.

These were very kindly donated by Helen Young who made the following comments regarding the reels
"There are 3 reels, the ends are a bit scruffy, although one (the blue one) has some blank tape at the end so is maybe complete. They have survived because many years ago they were useful for making Christmas decorations, and were at the bottom of our decorations box - which is why they have come to light just now!
I suspect that the tapes are from my days at Chelsea College and the Elliott 503(?) there, but I'm not sure. They look to be 8-track even parity, which is the only type I used apart from 5-track on the Elliott 803 which was in use when I first went to work for the college. They look to be binary dumps rather than code, as I can't see regular carriage return/line feed characters and there are no blank sections which we left between lines for splicing corrections etc."
The Macintosh Quadra 950 was the third desktop computer in Apple Computer's Quadra line. It was based on Motorola's 68040 microprocessor rather than the 68LC040 (which lacked an on-board FPU). It replaced the Quadra 900, increasing the CPU clock rate from 25 MHz to 33 MHz, and improving the graphics support. The two computers were otherwise identical.

According to Apple, the monstrous power supply can support two 25-watt NuBus cards and three of the more typical 15-watt cards.
The internal SCSI bus is terminated on the motherboard, so internal SCSI devices should not be terminated. This is the opposite of all other Macs except the Quadra 900. However, the external SCSI bus works the same as on other Macs.
Although there are two separate SCSI buses, System 7.0-7.1 "folds" them together so the operating system sees a single virtual SCSI bus. Thus, under System 7.0-7.11 (and only under those systems) you must make sure that all devices on both chains have unique IDs.
TrackMan Vista (1994) took trackball ease to new heights. Use just one finger to rotate the trackball. Your other fingers are free to use the top two buttons and the primary side thumb button without causing accidental cursor movement. TrackMan Vista gives you the advantage of three buttons and includes MouseWare software, which lets you assign draglock, double click, or another frequently-used command to one click of the third button. Customize your cursor. The Smart Move TM feature automatically places the cursor on default selection boxes.
An Amazon review states
"I went to the local computer retailer down the street from my house and looked over all the options. They had a thing called a Trackman Vista. It was a rollerball mouse. First I'd seen. And expensive for the time at $50. I walked around the store, talked to a couple of the sales guys. And after thinking about it a bit, I bought one.
It was the best $50 computer item I ever invested in. I'm still using it, and it's now 2008. My current computer is running XP and it works fine with it. In fact, I've bought 3 other Trackman Vista's over the years...all 2nd hand, to be used on my other newer computers. The computers and monitors have died off over the years, but the Vista just keeps a going."
Our mouse is in excellent condition and is with all the original packaging. This was kindly donated by William McDowell
The GRiDPad 1910 is the computer most commonly associated with the words "grid pad", AKA the brand name "GRiDPad", owned by GRiD. The first GRiDPad was introduced in 1989
The GRiDPad 1910 is basically an extremely portable PC-XT. It has a 640x400 backlit Monochrome touchscreen CGA display. It has 2MB of system memory, and often came equipped with a 20 MB 2.5" IDE disk. The pen system is capacitance-based, with a wired stylus. There is a 6-pin micro-DIN XT keyboard interface. Audio is limited to the usual PC Speaker support. There is one serial port expressed on the unit, and expansion for a modem, which came in 2400 and 9600 bps flavors. There are two ATA-FLASH slots on the unit, which are used strictly for storage. There is also an expansion bus connector on the bottom of the system, which includes at least a keyboard connector, a parallel port, and a floppy bus. There are buttons F1 through F5 and a sleep button on the unit, as well as a hard power switch. Power is supplied via Ni-Cad battery packs.
This unit was used primarily for inventory purposes and the like. Apparently it was used within Chrysler for that purpose, and by the United States Army. The military specified more rigidity and durability from the case than the civilian version provided, and so GRiD made the case out of magnesium. They were never sold to the public that way, but occasionally a unit will slide out of the hands of the military.

Dr. C.V. Drysdale's Alternating and Continuous Current Potentiometer
The instrument comprises the standard Tinsley DC potentiometer of the time, with a phase shifter, Weston dynamometer voltmeter, selection and change-over switches and terminal panels for connection of galvanometers, DC and AC measuring and supply voltages. Measures voltage as magnitude and phase from reference voltage.
Monash University, Department of Electrical and Computer Systems Engineering of Australia describes this machine as “Possibly the most technically significant or the measuring instruments” in their Graham Beard Memorial Collection
Massachusetts Institute of Technology, Boston in its reports of the President and Treasurer dated January 1913 states “The most important addition to the equipment of the Standardizing Laboratory made during the past year is a Drysdale-Tinsley alternating current potentiometer, with the necessary auxiliary apparatus.”
THE ALTERNATING CURRENT POTENTIOMETER. The potentiometer, which is the universal instrument by which currents are determined in terms of a difference of potential between the end of a known resistance, has been developed by C. V. Drysdale for the measurement of alternating potentials. The main circuit of the potentiometer must be supplied with alternating current of exactly the same frequency as that in the circuit to be measured, which means in practice that they must be supplied from the same source. Further, the phase relation between the circuit to be measured and that supplying the potentiometer may have any value from to 360. In order to obtain a balance, as indicated by the detecting instrument, it must be possible to give to the potentiometer current any phase displacement relative to that of the potential supplying it. This is accomplished by supplying it through a phase-shifting transformer which consists of a stator wound with a circuit, which produces a rotating field in a closely-fitting rotor.
The rotor has a winding on it which supplies the potentiometer current. A rotation of the rotor of the phase-shifting transformer through 360o has the effect of producing a phase shift of the same value, and a pointer on the rotor axis indicates the phase angle on a suitably divided scale. The "balance" is obtained by successive approximation of the usual adjustment of the potentiometer contacts (dial and slide wire reading) and of the phase-shifting transformer until the indicator shows no deflection. The indicator for low frequencies is a vibration galvanometer which must be closely tuned to resonate to the frequency of the circuit. For higher frequencies a telephone may be used. The main potentiometer current must be kept at some known constant value. This is done by switching it over on to a continuous current circuit, which is adjusted until a balance is obtained at the proper setting, when a Weston cell is connected up in the usual manner. The reading of a sensitive dynamometer type ammeter in the main circuit is noted. This ammeter must read correctly with alternating and continuous currents. The potentiometer - is then thrown on to the A.C.supply, which is adjusted so that the ammeter reads the same value. Arrangements are provided for reversing the ammeter in order to eliminate the effect of stray fields.
The phase-shifting transformer is usually supplied by single-phase current. To obtain the necessary field distribution a split-phase scheme is used, part of the excitation being provided by a circuit containing a condenser and a resistance in series. These are adjusted until the A.C. current in the potentiometer circuit is as nearly constant as possible, when the phase-shifting transformer is rotated to any position. As it is necessary to have the splitphase circuit somewhere near the resonating point, it must be adjusted for changes of frequency. As the vibration galvanometer has also to be adjusted for such changes, it is necessary to have a source of a very steady frequency and voltage for satisfactory working.

Deep Blue was a chess-playing computer developed by IBM. On May 11, 1997, the machine won a six-game match by two wins to one with three draws against world champion Garry Kasparov.Kasparov accused IBM of cheating and demanded a rematch, but IBM declined and dismantled Deep Blue.Kasparov had beaten a previous version of Deep Blue in 1996.
The project was started as "ChipTest" at Carnegie Mellon University by Feng-hsiung Hsu, followed by its successor, Deep Thought. After their graduation from Carnegie Mellon, Hsu, Thomas Anantharaman, and Murray Campbell from the Deep Thought team were hired by IBM Research to continue their quest to build a chess machine that could defeat the world champion. Hsu and Campbell joined IBM in autumn 1989, with Anantharaman following later. Anantharaman subsequently left IBM for Wall Street and Arthur Joseph Hoane joined the team to perform programming tasks.Jerry Brody, a long-time employee of IBM Research, was recruited for the team in 1990. The team was managed first by Randy Moulic, followed by Chung-Jen (C J) Tan.
After Deep Thought's 1989 match against Kasparov, IBM held a contest to rename the chess machine and it became "Deep Blue", a play on IBM's nickname, Big Blue. After a scaled down version of Deep Blue, Deep Blue Jr., played Grandmaster Joel Benjamin, Hsu and Campbell decided that Benjamin was the expert they were looking for to develop Deep Blue's opening book, and Benjamin was signed by IBM Research to assist with the preparations for Deep Blue's matches against Garry Kasparov.
In 1995 "Deep Blue prototype" (actually Deep Thought II, renamed for PR reasons) played in the 8th World Computer Chess Championship. Deep Blue prototype played the computer program Wchess to a draw while Wchess was running on a personal computer. In round 5 Deep Blue prototype had the white pieces and lost to the computer program Fritz in 39 moves while Fritz was running on personal computer. In the end of the championship Deep Blue prototype was tied for second place with the computer program Junior while Junior was running on personal computer
Deep Blue is a massively parallel system designed for carrying out chess game tree searches. The system is composed of a 30-node (30-processor) IBM RS/6000 SP computer and 480 single-chip chess search engines, with 16 chess chips per SP processor. The SP system consists of 28 nodes with 120 MHz P2SC processors, and 2 nodes with 135 MHz P2SC processors. The nodes communicate with each other via a high speed switch. All nodes have 1GB of RAM, and 4 GB of disk. During the 1997 match with Kasparov, the system ran the AIX r4.2 operating system. The chess chips in Deep Blue are each capable of searching 2 to 2.5 million chess positions per second, and communicate with their host node via a microchannel bus.
Deep Blue is organized in three layers. One of the SP processors is designated as the master, and the remainder as workers. The master searches the top levels of the chess game tree, and then distributes leaf" positions to the workers for further examination. The workers carry out a few levels of additional search, and then distribute their leaf positions to the chess chips, which search the last few levels of the tree.
Overall system speed varied widely, depending on the specic characteristics of the positions being searched. For tactical positions, where long forcing move sequences exist, Deep Blue would average about 100 million positions per second. For quieter positions, speeds close to 200 million positions per second were typical. In the course of the 1997 match with Kasparov, the overall average system speed observed in searches longer than one minute was 126 million positions per second. The maximum sustained speed observed in this match was 330 million positions per second.

BBC Model A Issue 1
Launched in 1981 to coincide with a computer literacy drive by the BBC, the Model A was the cheaper of Acorn's two machines at £299. The machine's high cost was compensated for by very impressive expansion possibilities including disc drives, a second processor and network capabilities (Econet).
Processor 6502A Speed (MHz) 2 Ram (KB) 16 Ram expandable to (KB) 32 ROM (KB) 32 Sound 3 channels plus noise Keyboard type Typewriter-style Number of keys 74 Dimensions (mm) 409 x 358 x 78 Weight (g) 3700 Interfaces Cassette interface(7 pin DIN) Composite video output(BNC)
The Acorn BBC model A was the successor of the Acorn Atom and its first name was Acorn Proton. It was a very popular computer in the UK and was widely used in schools, but it didn't have great success elsewhere (even though it did have great features, it was too expensive).
This computer got its name because in 1980, the BBC decided to start a computer literacy television series. The network realized that, with more powerful and increasingly inexpensive microcomputers, it would soon be possible to create them with enough computing power to offer their owners personal hands-on experience with microcomputers at an affordable price.
The BBC considered the NewBrain computer and rejected it. Acorn and Sinclair Research, along with other companies, then submitted designs, and Acorn won. The BBC Micro was then used almost universally in British schools from its birth into the 90's.
This model A Issue 1 is a very early machine and has a serial number of 100058
Rank Xerox ‘Telecopier 400’ facsimile machine, 1974. This ‘Telecopier 400’ facsimile machine was made by Rank Xerox Ltd in England. It is a multi-function device made for office use. In 1971 Rank Xerox introduced the first telecopier using the flat bed method of copying. In this system the paper is electronically scanned line by line on a diode ledge. The received signals are transmitted by telephone and then also transferred line by line onto an electrode comb which charges the paper electrostatically to reproduce the original image.

The Newton Connection Kit allows your Macintosh to communicate with your Newton. You can backup and restore Newton data, examine the data on your Macintosh and download Newton software applications to your Newton.
The first time the Newton Connection Kit synchronizes your Newton with your Macintosh, all the information from your Newton will be copied onto your Macintosh's hard drive. After the first time, synchronizing will copy only new or changed information from Newton to your Macintosh or vice versa. When synchronization is completed, the identical information exists both in the Newton folder on your Macintosh's hard drive and in your Newton.
When you synchronize, all information you deleted since the previous synchronization is stored in an Archive file on the Macintosh. The entire file left by the previous synchronization will be stored as a file called "Backup."
Our kit was kindly donated by Bill Henley
The Apple Newton MessagePad 110, codenamed Lindy, features a 20 MHz ARM 610 processor, 4 MB of ROM, 1.O MB of SRAM (480k usable), and infrared-beaming capabilities in a sleek handheld case with a 320x240 pressure-sensitive monochrome display for use with a provided stylus. Compared to earlier models, the Newton MessagePad 110 provides a rubberized housing that is slimmer and more comfortable to hold, more RAM, greater battery life, and an improved version of the NewtonOS (1.3).
This is the Apple machine which launched the "PDA" trend. John Sculley, Apple CEO at the time, invented the "Personnal Digital Assistant" term to name a new breed of products that the Newton would define.
The Newton MessagePad was one of the first series of handheld systems, or PDAs (Personal Digital Assistants), to attempt to recognize natural handwriting and use a basic form of artificial intelligence to 'tie' relevant information together. Newtons are technically not 'Macs', as they do not operate the MacOS, and instead use the NewtonOS (also developed by Apple).

Our eMate is in very good condition with the original box and packaging. It is complete with all manaus, software and cable.
The model No: is H0149 with a serial number of JE7253LK98UX and was very kindly donated by Bill Henley
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.

The Watford electronics bbc speech synthesizer uses an allophone system to give the user an unlimited vocabulary and the capability to speak any english word. The advanced software described in this manual offers the user a built in word library, and a 62 allophone buffer under interrupt control with access from any language via the *TALK command, OSBYTE, OSWORD and *FX25. It has been specially designed so that the user can design his own words to be spoken. Use of a speech buffer means that the computer can carry out the user's programs while the unit is speaking with minimal effect on program speed.
The speech synthesizer consists of a box with a built in speaker and volume control, a lead to connect with the computer and a jack socket for connection to an external amplifier such as your Hi-Fi or personal radio/tape player.

The AMX mouse was a 3 button mouse which plugged into the BBC Micro's User port. the software to drive it was in a sideways ROM. The AMX mouse came with the AMX Art application.
"The AMX Mouse together with the accompanying ROM and software represent a major advance in home computing, making the BBC computer much easier to use for the average person: Together they represent remarkable value for the BBC owner, and transform the machine into a much more user friendly device, comparable with much more expensive machines. The Mouse may be used with any BBC Model B computer with either cassette or disc filing systems, and draws its power from the User port. For the more advanced user, routines contained in the ROM allow programs to be written in Basic or Assembly language which incorporate many of the latest features including icons, windows and pointers.

Microscribe works just like any other terminal, with keyboard input and visual display output. The big difference is that where other terminals dominate the work surface, Microscribe is little larger than a textbook. It can even fit easily into a briefcase. Yet it is rugged enough to stand uptoeveryday use in industrial applications. It uses the industry standard RS232 serial interface protocol, so it can communicate with virtually any host computer or periphera either directly or via modems or acoustic couplers. A battery operated version using low-power CMOS technology is ideal for field or mobile use, acting as an electronic notebook or data capture device. For dedicated applications, where the terminal is permanently linked to and powered from a host computer there is a standard low cost NMOS version. An optional AC adapter provides power and can act as a charger for the battery versions.
Microscribe gives a single line display of 16, 32 or 40 alphanumeric characters with true descenders. Special control circuitry in the battery-powered models ensures that the contrast ratio of the display remains constant during the full discharge curve of the battery.
The keyboard is microprocessor controlled, and each key has full travel and tactile response, with selectable audio feedback. It is designed for years of trouble-free operation — the switch pads, for example, are made of pure gold. Setting up the terminal to suit a particular role is carried out interactively via the keyboard, and a range of preprogrammed function keys simplifies frequently-used operations.
Superb styling, careful ergonomics and innovative electronic design makes Microscribe the ideal terminal for today's industrial and commercial computer systems. Its size and power brings new dimensions to applications hitherto considered impractical for reasons of cost, environment or space."

The Fluke 9010A Micro-System Troubleshooter is self-contained programmable unit designed to locate faults in microprocessor-based systems. The 9010A includes built-in pre-programmed test routines for checking the entire microprocessor kernel including the bus, RAM, ROM, and I/O. The 9010A comes with a troubleshooting probe that can be used to either monitor logic action on a node-by-node basis or to inject stimulus pulses. The 9010A uses microprocessor-specific interface pods to interface to the suspect circuit board. Over 50 different pods are available supportin an extnesive list of microprocessors. The interface pods have extensive protection and self test features ensuring confidence in troubleshooting and testing circuit boards. Each pod contains its own microprocessor, RAM, ROM, and I/O memory space permitting it to test non-functional boards. The 9010A has a mini-cassette for storing and reading programs and memory maps from the unit under test.
This is designed to troubleshoot and test microprocessor based systems with test routines for locating faults related to the microprocessor bus (RAM, ROM, I/O). The unit includes a probe to monitor logic action on a node by node basis or to inject stimulus pulses. The unit is a self contained programmable model that lets you develop your own customized programs. They can use prerecorded cassettes or be programmed from a PC. It also includes a LEARN algorithm that will generate a memory map form a known good board. The unit supports a large list of older microprocessors, such as 8086, 8088, Z80A, and many others.
Key Points: •Micro System Troubleshooter •Troubleshoot microprocessor based boards with ease •Microprocessor interface pods for over 50 microprocessors •Perform BUS, ROM and RAM testing with a few key strokes
One of the benefits of using the 9010A, is that you can create scripting test suites. All Fluke 9010A Troubleshooters have a microcassette tape system. However, this requires that you manually key in programs -- a long and error-prone process.

Microwriter AgendA
The Microwriter AgendA was one of the first PDAs. Released in 1989, it includes a set of small "conventional" keys arranged inside the half circle of a Microwriter chording keyboard with larger keys. It has 32k of storage, pluggable memory modules, a 4-line LCD screen, and advertised excellent build quality and long battery life. It was designed for text-mode note-taking without a conventional desk or keyboard. In 1990 it was awarded the British Design Award.
Microwriting is the leading system of chord keying and is based on a set of mnemonics, it was developed by Cy Endfield and Chris Rainey in the 1970s. The system was used in the Microwriter and the Microwriter Agenda, which was one of the first PDA (personal digital assistant). The AgendA was awarded the British Design Award in 1990. Thousands of people have acquired the ability to use the system. Most people can touch type in less than 1 hour but many in 30minutes. Then typing speed and accuracy will build up as experience is gained.
The Microwriter codes can be seen at http://www.bellaire.demon.co.uk/bellaire_cykey_codes.html

The Compaq SLT/286 (1988), prices starts at $5,399.
The machine offers a bright high-resolution display that supports the VGA video standard, the first laptop with that feature. It has a 12-megahertz 80C286 processor, a new low-power chip that is among the faster 80286 microprocessors, and it is certainly capable of handling most applications. And it has a detachable keyboard, another first among laptops.
It is 8 1/2 inches deep - 2 to 3 inches less than the other leading laptops at the time
The SLT/286 provides mass storage in the form of a 20-megabyte or 40-megabyte hard disk drive. The shock-mounted drive is a new design that can withstand up to 80 G's of impact, or a ride in the trunk of a New York City taxi, whichever comes first. Data is transferred through a high-capacity (1.44 megabyte) 3.5-inch diskette drive. An optional 2,400-baud internal modem is $599.
At 14 pounds, including the battery and the hard disk, the SLT/286 strains the definition of laptop. Still, it is five pounds lighter than Compaq's lunchpail-shaped Portable III, a significant difference among portables. Most important, it runs for three hours on one battery charge. An optional backup battery pack ($129) weighs two pounds.
One drawback of the machine is that it does not support color, but then neither does any other laptop. (High-resolution flat-panel color displays will begin arriving next year.) Another surprise is that Compaq, which has forged its reputation for high-performance machines around the 80386 microprocessor from the Intel Corporation, did not introduce an SLT/386. While the 12-megahertz 80C286 is a better-than-average chip, it is no match for the 386 chip. Michael Swavely, Compaq's vice president for marketing, suggested in an interview that the power demands of the 386 chip had reduced the SLT's battery life to unacceptably short periods. The fast 286 chip, he said, offered the best balance of performance and battery life.

The A305 and A310 were launched in June 1987. It was the first RISC CPU based computer in the world. There were 2 models, the A305 and the A310. The A305 could be upgraded to the A310 specification.
The RISC-based A310 excelled on integer programs, but the lack of FPU showed up in the 'Savage' benchmark, where slow IEEE-754 compatible emulation routines in the C library hurt the performance. Remarkably, the A310 could run Savage in interpreted BASIC in 32.8 seconds, only about 50% slower than the Compaq Deskpro 386 equipped with a 80287 math coprocessor.
The A310 ran an operating system called Arthur. It was based on earlier OS Acorn wrote in 1979 for the BBC Micro, a 6502-based PC. Arthur was quite modern for a PC and included features like modularity between the OS and file system (two different file systems were supported), a graphical user interface (GUI) called Desktop, and a built in scripting language. A310 was installed with an ARM2 processor and 1 MB RAM
From the Archimedes brochure: "The Archimedes 310 personal workstation - world beating technology in an affordable microcomputer. The Archimedes range of microcomputers represents a British breakthrough in the application of RISC technology to personal computing. Acorn has designed and developed the RISC microchip for the Archimedes range to bring practical benefits to all microcomputer users.
Acclaimed at its launch with the British Microcomputing Awards 'Micro of the Year' title, the Archimedes system has also won the 1988 TOBIE award for Best New Technology Application of the Year. In the words of Personal Computer World magazine, The fact is that the ARM chip is amazing, and the Archimedes which uses it is equally wonderful.
CENTRAL PROCESSING UNIT ARM (Acorn RISC Machine) 32-bit microprocessor using Reduced Instruction Set Computer technology. A typical execution rate of 4 MIPS (Million Instructions Per Second) makes the Archimedes system the world's fastest microcomputer in its class to date.
MEMORY 1 Megabyte of fully addressable built-in RAM. Complex software applications to run from RAM without frequent delays for disc reading. Long documents and large quantities of data to be held in memory for faster processing. 512 kbytes of ROM store the complete operating system and the BASIC programming environment, along with the window driven user interface. The Archimedes system is ready to run as soon as you switch on. You do not have to load the operating system from disc. Storing the operating system in ROM makes more RAM available for applications."

With the PC-1251, Sharp started off their product range of really tiny pocket computers. It was the third original design after the PC-121x and PC-1500 series.
Contrary to its predecessors, it was really pocket sized, measuring only 135 x 70 x 9.5 mm. Nevertheless, it featured a 24 character display, and with 4 KB RAM it even outclassed the PC-1500 basic version. The major drawback of the new design was that the tiny keys are only compatible with pointed fingers.
The PC-1251 was based on a new 8-bit CMOS micro processor, the SC61860, which was mounted on the main PCB together with the display driver chip SC43536. On an additional small PCB, 24 KB ROM (LH532917) and 4 KB RAM (two HM6116 2k x 8 chips) were located. A new feature was the so-called "reserve memory" which allowed to assign often used BASIC commands or functions to 18 of the alphanumeric keys.
Together with the PC-1251, the CE-125 thermal printer and micro cassette recorder unit was introduced. With integrated NiCd accumulators, it was fully mains independent and made the 1251 into a very compact mobile computing system. The CE-125 also featured an additional tape interface for external tape recorders.
The PC-1250 was the same machine as the PC-1251 but with only 2 KB of RAM.

Sinclair Cambridge Type 1 Calculator This we believe is the first model of the Cambridge range 1973. It had a brown colour and was suppluied with a white hinged polypropylene type protective case. Ors is complete with the operating Instructions and has a serial number of185607
8 digits, red LED. 4-functions, constant. Has [C] and [K] (constant) keys. Batteries: 4x AAA. Main integrated circuit - General Instruments Microelectronics GI-C550, here date coded mid-1973. 50 mm x 111 mm x 28 mm (2" x 4.4" x 1.1"). Made in England. The first of the very small Sinclair Cambridge series, introduced in Summer 1973, costing in Britain £43.95 Sterling (US$105). The case has a glossy finish, with a poorer quality moulding than usual for Sinclair. The main chip is in a more expensive ceramic package.
This was many people's introduction to electronic calcs. It was tiny, affordable, and it outsold just about any other model in the UK. It also had a lifespan of several years during which the price dropped nearly tenfold! A classic, and the product Sinclair is most often remembered for (apart, maybe, for the computers). It was also available as a kit (can you imagine a kit calculator nowadays?!)

The fx-602p released around 1982 is thought by many as the finest calculator casio ever made. An evolution of the fx-502p with more memory and an alpha-numeric display. it was the last of the casio step programmables and alpha was added to compete with the hp41c. hereafter, casio moved onto basic programmable pocket computers like the fx-700p, although for a time, this model was concurrent with the fx-702p which wasn't sure whether it was a pocket computer or a calculator. the 10+2 display also accommodates 11 alpha characters consisting of upper and lower case letters together with many useful symbols. the display is clear for a dot matrix type. there is no external contrast control, but the display contrast could be adjusted with a potentiometer after opening the unit.
The unit is programmable with constant memory, totalling of 512 steps and 22 memories (M00-M19 plus MF and M1F). this number can be partitioned, trading in steps for more memories. between 22 and 80 memories are allowed corresponding to between 512 and 32 steps. the base memories cannot be converted into more steps than 512. When you altered the memory partition to gain more memory registers (at the cost of 8 program steps for each memory register), you always got an extra F Register for every 10 Memory registers. If you had M20-M29, you also got M2F as a bonus. Where this extra memory space came from, I don't know.
Programmability is the same as the fx-502p with a comprehensive set of instructions including 4 tests, isz & dsz (increment/decrement and jump if zero) for compact loops, labels, subroutines and indirect addressing. The original F Register (located at the EXP key) was used for number comparisons. There were 4 kinds of comparison: x=0, x?0, x=F and x?F. Although the F register played an important role, there was nothing special about the other F Registers.

Herman Hollerith's Type 001 Mechanical Card Punch, patented in 1901, was the first key punch; that is, the first card punch operated from a keyboard, so that the operator could punch digits 0-9, without knowing the corresponding card codes. Of this device, Hollerith said "My invention ... comprises a traveling carrier for the card, a series of key-operated punches arranged at right angles to the path in which the carrier moves, so that in any position of the card either the cypher or any of the nine digits may be punched by the operation of the proper key
The punch was patented by Herman Hollerith on the 10th September 1901 - see picture

The Magnetic tape collection. (from left to right…)
Cambridge Computer Services tape number 10000002 meaning it was almost certainly the second (2400ft) tape to be written to after the ICT 1903 was installed in 1966. (Early tapes were available in 2400ft, 1200ft, and 600ft sizes and most could be recorded at 600 bpi)
A Pericomp Beginning of Tape (BOT) guillotine. The tape leaders got very creased and frayed in constant use and this device (or a pair of scissors) tidied them up (until you ran out of leader.
Write Permit Rings (available in many colours) WPRs were inserted into the back of the tape spool to allow writing or removed to prevent overwriting. (the source of many a tape reload or rerun) If you think about it you only needed one ring per deck, maybe 4 and a couple of spares, but because every tape was supplied with one computer rooms tended to be littered with them.
A later ICL 600ft (Tupperware) mag.tape. The Tupperware nickname came from the semi-opaque plastic case they were supplied in to make transit safer.
