This expansion card shipped inside the Xerox 820-II as standard. It provided support for external data storage drives, which can be dual 5 1/4-inch floppy drives, dual 8-inch floppy drives, or the 20Kg 8-inch floppy and rigid drive combination unit. Drives were supported in several combinations and could be daisy-chained with the secondary connection on the drive unit rear. The default drive assignments were A-D for floppy drives and E-H for hard-disc partitions.
The Xerox 8/16 was the successor to the Xerox 820 series. It has two CPUs: an 8-bit Z80 for running CP/M and an 8086 for MS DOS or CP/M-86. The power supply, display, and disc system weere shared between the two processors which were otherwise independent. This computer was one of the first desktop computers to feature concurrent processing : a task could be started on one operating system and, with a special keyboard command, the user could switch to the other processor to perfom another. Both processors could work at full speed as they shared no RAM or system resources. Only the input/output devices were locked to the user's active processor.
Our Xerox 8/16 is pictured here with the 8-inch floppy drive and hard drive unit.
Manufactured by ASCII Corporation, the Mega Stick is a three-button joystick for the Sega Mega Drive. It was released in Europe as an official SEGA product. In America and Japan it was a third-party peripheral marketed under the names "Power Clutch SG" and "Cluster Stick", respectively.
The Mega Stick an eight-direction joystick, variable speed autofire f or the A, B, and C triggers, and a 'slow-motion' toggle. As with all such peripherals, this was implemented as an auto-fire for the start button. The slow-motion was dependent on the game interpreting this as the player rapidly pausing and unpausing the game.

The Microwriter is a hand-held portable word-processor with a chording keyboard. It was sold in the early 1980s by Microwriter Ltd, of London, UK. Microwriter was invented by UK-based, US-born film director Cy Endfield.
The 23 cm x 12 cm x 5 cm device comprises:
- A six-button chording keyboard.
- A single line LCD display.
- An 8 bit microprocessor.
- Complete Word processing software in ROM.
- 16 kilobytes of RAM.
- Rechargeable Nickel-cadmium batteries - sufficient to run the device for 30 hours.
- Various interfaces (see below).
This device is capable of allowing the user to enter and edit several pages of text - and by connecting a printer to the RS-232 serial port connector, documents can be printed without the aid of a separate computer.
The keyboard uses one button for each finger and two for the thumb of the user's right hand. The five buttons immediately beneath the fingers are pressed in different combinations to generate all letters. The second thumb button is used to toggle through a range of modes that allow the user to switch case, enter numbers, insert punctuation and even add ASCII control characters, to be used in editing the document being prepared. To type a letter "T", for example, the user would tap the top thumb button to shift to uppercase, then chord a "t" by pressing the index finger and ring finger buttons simultaneously.
The manufacturers claimed that most people could learn to use it in just a couple of hours. With some practice, it is possible to become a faster typist with the Microwriter than with a conventional keyboard, providing that what is being entered is just text. Typing is slowed if a substantial number of special characters have to be entered using the "shifting" mechanism.
Learning the chords for the basic letters and numbers is facilitated by a set of flash-cards that show simple mnemonics for each character.
Despite a lack of similar products, the Microwriter was not a success, and ceased production in 1985. It is likely that the concept of a chording keyboard put off many potential customers.

This third-party cassette recorder is designed to be used with the Commodore VIC20 and VIC64 home computers.
This calculator was designed in 1967 but sold into the early 1970's. Most of the logic is constructed from discrete transistors and resistor-diose gates, but some small-scale integration silicon IC's are also used. Despite the name on the case, the design and manufacture was actaully carried out by Sharp Corporation. Two memory registers are provided based on magnetic core memory. They therefore retain their values when power is turned off.

This INMOS B008 PC Board was designed to plug into a standard IBM-compatible PC and allow it to control up to ten Transputer Modules ("TRAMs"). While different motherboards were developed for different host systems, the TRAMs were universal modules, each hosting a Transputer processor and up to four megabytes of RAM. Multiple B008 cards could be installed in a single PC, each chained together and controlled by a single 'master' board. Each TRAM could also act as a master controller for a separate subsystem of Transputer modules. All Transputer processors require a standard 5MHz external clock - high-frequency clocks are internally derived from this. The B008 Transputer processors internally run at 20MHz.
The motherboard contained an IMST212A processor and an IMSC004B processor to handle comunications between the TRAMs and the PC interface.
The IMST212A is a 16-bit processor containing 2KB on-chip RAM; up to 64KB external RAM is supported. It incorporates a pre-emptive microcoded scheduler, enabling any number of concurrent processes to be executed without a software kernel. Two hardware timers are available with 1-microsecond and 64-microsecond precision, respectively. Four identical bi-directional serial links are the 212's interface to the outside world. Each link has input and output channels, with TTL compatible signals at a standard 10Mbit/sec.
The IMS C004 is a transparent programmable link switch designed to provide a full crossbar switch between 32 link inputs and 32 link outputs. The IMS C004 will switch links running at either the standard speed of 10 Mbits/sec or at the higher speed of 20 Mbit/sec. It introduces, on average, only a 1.75 bit time delay on the signal.
This B008 motherboard is fully populated with four double-width TRAMs and two single-width. The TRAMs are:
- Four IMSB404 modules with IMST800 processors and 2MB RAM. 4KB is internal to the Transputer (1 cycle access time), 32KB is SRAM (3 cycles), and the remainder is DRAM (4-5 cycles).
- Two unknown single-with modules with IMST424A processors, possibly 1MB RAM.
The SPARCbook 2 was a portable SPARC system produced by Tadpole Technologies in the early 1990's. Retailing for $10,950 the standard configuration shipped with 16MB RAM, a 250MB hard disk, and a 640x480 colour TFT active-matrix LCD display. No floppy drive was included as standard, although external SCSI floppy drives were available.
This pre-production thin client was designed to support Citrix Systems WinFrame and MetaFrame. Based on the ARM7500FE, this reference design was intended to be licensed to other manufacturers. The DeskLite was one of the last products launched by Acorn.
Our DeskLite has serial number 009 and is part of the Chris Whytehead collection. Further details, including images of the internals, are available on the Chris Whytehead site.
The Gold Card was the first Miracle Systems board to replace the QL's 68008 processor. With 2MB RAM and a 16MHz 68000 processor, it could roughly quadruple a QL's performance.
1920K of the memory is directly available to the QL; the remainder is used for display memory and shadowing the QL and Gold Card's ROMs.
The Gold Card has a disk drive interface connector capable of supporting up to three disk drives. Double Density (720K), High Density (1.4MB) and Enhanced Density drives were supported, and the connector was backwards-compatible with the older Miracle Systems Trump Card.
The Gold Card has a battery backed clock, whose time and date are copied to the QL's inbuilt clock at startup.
Supplied on the built-in ROMs were the Toolkit 2 and level 2 directory drivers for floppy discs and RAM discs.
The Gold Card attaches to the QL via the standard interface slot.
This expansion board for the BBC Micro plugs into the 6502 socket and provides four ROM sockets plus shadow RAM.
When the Ace Card 256K is plugged into a Sinclair QL an extra 256K RAM is added to the QL's own memory to give 384K RAM total. The Ace CArd was also marketted under the name "Trump Card".
A peripheral from Sinclair Research for its ZX Spectrum home computer, the ZX Interface 1 was launched in 1983. Originally intended as a local area networkinterface for use in school classrooms, it was revised before launch to also act as the controller for up to eight ZX Microdrive high-speed tape-loop cartridge drives. It also included a DE-9 RS-232 interface capable of operating at up to 19.2 kbit/s — a rare instance of Sinclair using an industry-standard connector. At hardware level it was mainly a voltage adapter, the serial protocol being implemented in software bybit-banging. This led to problems when receiving data, but not when transmitting.
A wedge-shaped device fitting underneath the ZX Spectrum, ZX Interface 1 contained 8 kB of ROM comprising the control software for the Microdrives, RS-232 port and network interface. This extended the error handler in the Sinclair BASIC to allow extra keywords to be used. As this became an official standard, other developers quickly used this mechanism to create language extensions to Sinclair BASIC.
This keyboard was used by the Navy, possibly to control a radar system. It has an integrated trackball. The keycaps are similar to those used by the Sinclar QL.
The Model N40 was PowerPC-based notebook developed and manufactured by Tadpole Technology for IBM. It became available on 25 March 1994, priced at US$12,000. It was powered by a 50MHz PowerPC 601. It had between 16 and 64MB RAM.
Kempston produced a number of joystick interfaces for the Sinclair ZX Spectrum to allow normal Atari-style DE-9 connector joysticks to be used with it. Apart from implementing existing joystick interfacing modes they produced their own standard which delivered the joystick state on the Z80 bus at port 31 (read in BASIC using IN 31). This meant that the joystick did not produce key-presses like the other standards and the method was soon borrowed by other interface manufacturers and became quite popular.
This model allows the connection of up to 3 seperate joysticks via 9 pin d plugs as well as a rom pack via the use of an adaptor. The one we have is complete in box.
An official joystick manufactured by Commodore for use with there various systems. No specific consoles are mentioned on the box. The stick has one button and an 8 way directional stick. It connects via 9 pin plug simaler to that of the Atari 2600 and Sega Master System.
The ZX81 is a home computer produced by Sinclair Research and manufactured in Scotland by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and was designed to be a low-cost introduction to home computing for the general public. It was hugely successful and more than 1.5 million units were sold before it was eventually discontinued. The ZX81 found commercial success in many other countries, notably the United States, where it was initially sold as the ZX-81. Timex manufactured and distributed it under licence and enjoyed a substantial but brief boom in sales. Timex later produced its own versions of the ZX81 for the US market – the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorised clones of the ZX81 were produced in a number of countries.
This model has been fitted with a 3rd party upgrade to the keyboard. It is a large, plastic device that is glued over the original keyboard to make the buttons larger and easier to hit.
