AVIE A300 2 Slot Backplane

The Acorn Archimedes A300 range did not include a backplane to allow expansion podules to be added to the computer. Acorn produced a 2 slot backplane and so did a number of 3rd parties including AVIE.

IFEL A410, 440, 680 Backplane

A four slot backplane manufactured by IFEL, for use with the Acorn A410, A440 and A680.

Acorn A410, 440, 680 Backplane

The ArchimedesA400/1 range was shipped with this podule backplane. It was also used in the A680 and R140 which ran RISCiX. The metal bar across the back secured the backplane to the computer's chassis.

The main difference between this backplan and the backplane on the earlier A440 was support for interrupt masking which allows interrupts from each podules to be set to a different priority. This improves performance and was needed for RISCiX

Irlam Instruments 24i16

The Irlam Instruments 24i16 is a 24 Bit Real-Time Video Digitiser & 16 Bit Sound Sampler.

Video is accepted from any composite or S-Video source including Video Recorders, Camcorders, Video Cameras, VideoDisc players and Still Video Cameras.

The standard digitiser allows a full television field to be captured in real-time(20 milliseconds). This can be extended to allow still images to be obtained up to fullTV frame size, which is useful for capturing really impressive stills fromcameras such as Sony Mavica, Canon ION RC-560 or Video Visualizer.

Built-in scaling hardware allows image sizes smaller than fields or frames to be captured. Filtering circuits anti-alias the scaled images in two-dimensions so that smooth images are produced. Moving sequences can be saved direct to disc at up to 25 images per second (ips). Note that image size and rate of capture is limited only by disc and system bandwidths, whichmeans that movies can be obtained at a wide range of sizes, rates and aspect ratios.

24i16 boasts a 16 bit stereo sound sampler which records (and plays back) at Compact Disc and Digital Audio Tape frequencies. Samples are recorded direct-to-disc giving virtually unlimited duration. A special resource allows the audio tracks from Replay movies to be played through the 16 bit output of 24i16 which dramatically improves their audio quality. Raw audio from the Acorn sound system can be filtered and mixed in with the 16 bit output to give improved sound quality.

A sophisticated RISC OS application supplied allows 24i16's features to be accessed quickly and easily. Image size, capture rate, audio sampling frequency and file format can all be controlled from the desktop. Video is monitored on-screen (and displayed in true colour on 16/32 bit desktops). Contrast, brightness, saturation and hue are software adjustable. Audio may be monitored using an oscilloscope display and/or VU meters. You can also hear the audio using the 16 bit output from 24i16 or via the speaker of your A5000, RISC PC etc.

The recording process works just like a cassette recorder; connect the audio/video source and press the record button, then press stop when you have captured the desired amount (or set a pre-defined duration). You can even perform time-lapse capture so that movies can be made of flowers opening or clouds forming etc. Documentation supplied includes details and examples of how to operate 24i16 simply from your own software written in BASIC, C or Assembler.

D.T. Software IDE Hard Disc Interface

An IDE interface made by D.T. Software in January 1990.

APDL ARCIN v6c IDE Interface

The APDL ARCIN IDE interface is made by Baildon Electronics . It is designed for Risc PCs and A7000s. The ARCIN interface can support up to 4 IDE devices (1 Master and 1 Slave on each socket) and can either replace or work with the motherboard ADFS Interface. The ARCIN interface transfer speed is about 3.6MB/sec sustained or up to 4.5MB/sec burst on a Risc PC or A7000, which is about twice the speed of the ADFS interface.

The APDL ARCIN IDE interface has been replaced by the APDL Blitz or Unipod IDE Interfaces.

Further details, including a HTML manual and the latest software is available from APDL .

Acorn RiscPC 2 Slot Backplane

This is a 2 slot backplane for a RiscPC. A RiscPC normally has a 1 case slice, but can be expanded by adding extra case slices to provide space for more storage deivces,. The backplane can be extended into the extra case slices with 4, 6 or 8 slot backplanes. The backplane plugs vertically into the motherboard on the right hand side next the the power supply fan.

Philips CDi Pre Production 180/181/182/ Professional Multimedia Console

This is a pre production model of the Philips 180/20 machine, which was a professional version of the CDi family aimed at the education market.

Jointly developed by Philips and Kyocera, the machine has 3 units, the top one is the CDi 180.

The middle unit is the MMC 181, or Multi Media Controller, this was for video output, and also houses the input ports and volume control, it also has an IC slot for 8K cards, replaced in later machines by a time keeper chip.

The bottom unit is the 182 expansion rack, which was used for authoring purposes, with two 3.5 floppy drives, scsi, printer and parallel ports.

Only the top two units are needed for operation.

The Philips CD-i (Compact Disc Interactive) is an interactive multimedia CD player developed and marketed by Royal Philips Electronics N.V. This category of device was created to provide more functionality than an audio CD player or game console, but at a lower price than a personal computer with a CD-ROM drive at the time. The cost savings were due to the lack of a hard drive, floppy drive, keyboard, mouse, monitor (a standard television was used), and less operating system software.

CD-i also refers to the multimedia Compact Disc standard used by the CD-i console, also known as Green Book, which was developed by Philips and Sony (not to be confused with MMCD, the pre-DVD format also co-developed by Philips and Sony). Work on the CD-i began in 1984 and it was first publicly announced in 1986. The first Philips CD-i player, released in 1991 and initially priced around USD $700, is capable of playing interactive CD-i discs, Audio CDs, CD+G (CD+Graphics), Karaoke CDs, and Video CDs (VCDs), though the last requires an optional "Digital Video Card" to provide MPEG-1 decoding, as do some of the machine’s better games, this additional cost made the machine prohibitively expensive compared to rival systems, such as the Snes and Megadrive, this version of the CDi could not be extended with the DGC.

The CD-i proved to be a commercial failure in that market segment, Philips ceased publishing video games for the platform in 1998.

Among the system’s weaknesses are just having 2 channels for sound, meaning that music for games must be in one, and sound effects in the other.

The machine is probably best known for being home to some Nintendo licensed games, products of a deal struck between the two companies when Nintendo cancelled a proposed CD drive for the SNES, three Zelda games and one featuring Mario were well received at the time, but thanks to internet folklore, they are often met with derision.

This is the first edition of the console.

Casio FX-7000G graphing calculator

The Casio fx-7000G is notable for being the world's first graphing calculator.

It came with 422 bytes of memory and it was possible to store up to ten programs in 10 program slots. 422 bytes is not much by today's standards but with its heavily tokenised programming language, programs performing fairly large tasks could be written.

It was a milestone in the history of pocket calculators when Casio introduced with the fx-7000G the world's first Graphing calculator. The display could be switched between the character mode offering 8 lines of 16 characters each, and a pure graphics mode with an array of 63*95 addressable dots. Even todays Graphing calculators like the TI-83 Plus kept this display format, main differences are the data and program memory sizes. Instead of limited 422 program steps todays calculators deal with megabyte instead the bytes.

Date of introduction: October 1985
LCD dot matrix
New price: $90.00 (SRP 1988) Display size: 8 * 16 characters

Acorn CAO50 Multimedia Expansion Unit

The Acorn CAO50 Multimedia Expansion Unit (M.E.U) was launched in 1993 and designed to provide multimedia features (CDROM and improved sound) for the early 32 bit Acorn Computers from the A3xx through to the A5000 and A4000.

Semerc Acorn A4000S

The Semerc A4000S was devised and developed through a partnership between Acorn Computers, SEMERC, Cumana as a complete system for users with special needs.

The system came fully configured and ready to use apon plugging in. The A4000S came with software is pre-installed, including Phases 3, My World, special needs utilities and programs from Brilliant and Widgit. The revolutionary Cumana EMU interface with standard user port allowed existing equipment, such as overlay keyboards, switch boxes, control equipment and turtles, to be connected immediately using existing leads. The EMU interface also permited further expansion.

The A4000S came with comprehensive support literature, including guidebooks and starter guide. Helplines were also available from Acorn, SEMERC and Cumana and support from a nominated dealer.

Price wise, the A4000S with a standard Acorn colour monitor retailed for £899 (plus £10 deliver per system), excluding VAT. The Acorn A4000S with multiscan Acorn colour monitor retailed for £949 (plus £10 delivery per system) exluding VAT.

Maplin ZX81 Talk Back GB18U

The Maplins ZX81 Voice unit that plugs into an expansion I/O board.

Talk-Back was a speech synthesis electronics kit designed by Dave Goodman sold by Maplin in 1983. The Talk Back allowed you to add speech to your programs using a programmable digital filter which simulates the human voice tract.

There was no ROM on the PCB. You made it talk by POKEing it. So, this device did not take up any RAM.

Apple iSight

The Apple iSight was first launched in 2003.

The Apple iSight retailed at US$149 and connected to a computer via a FireWire cable.

The external iSight's ¼-inch color CCDsensor has 640×480-pixel VGA resolution, with a custom-designed three-part F/2.8 lens with two aspherical elements. It features autoexposure, autofocusing from 50 mm to infinity, and video capture at 30 frames per second in 24-bit color with a variety of shutter speeds. However, the iSight has an image delay of approximately 120 ms.

The iSight incorporates internal microphones with dual-element noise suppression. The actual camera only takes up one-quarter of the unit; the remaining space is primarily occupied by its two microphones and mounting socket.

Four camera mounts, a plastic tube carrying case and a FireWire camera mount adapter are also included. The user can select the mounting bracket most appropriate for their monitor or other mounting surface. It is fully compatible with its native macOS, as well as partially compatible with the Microsoft Windows and Linus operating systems.

The iSight has a small green LED that illuminates when the camera is in use. It also has an iris that closes by twisting the front of the camera.

Atari 850 Interface Module

The Atari Serial Input/Output System or SIO was designed to allow the computer to communicate with peripherals such as the 810 or 1050 disk drive. An advantage of the SIO is that multiple devices could be chained together. A major design consideration was allowing the computer to communicate with peripherals without the need for installing an internal card.

Unfortionatly, a number of devices such as third-party printers used a differnt port called the RS-232. Atari made the 850 Interface Module to allow communtication with devices that used the RS-232 port.

Gravis Analog Pro Joystick

Some joysticks are designed specifically for flight simulation programs and others for action arcade games. The Garvis Analog Pro Joystick incorporates these specialized features into a powerful multi-purpose joystick that allows you to play all your favorite games like a pro.

The Gravis Analog Pro Joystick was Factory Calibrated for top performance, it has recessed trim adjusterers and Long-life potentiometers and microswitches. It connected to a standard game port and came with a 1 year 'no-nonsense' warranty.

For Flight Simulation the Gravis Analog Pro offers smooth analog control, built in throttle control, throttle 'off' feature to avoid second joystick conflicts, and 5 fire buttons.

For Arcade Action the Gravis Analog Pro offers adjustable button functions, support for four independant buttons, adjustable handle tension and a full sized padded handle.

This model pictured is for the IBM PC and compatables

Sega Control Stick

The official Sega Contol stick is designed for right handed control, instead of the typical left handed set-up.

The Control Stick was released in 1987.

The Control Stick functions exactly like a standard Sega Master System control pad but attempts to give users a greater sense of control over on-screen charactors. It is however, not so good that require precise movements.

Some versons of the Control Stick freely advertised its compatability with other home computers of the time, such as the Commodore VIC-20, Commodore 64, Atari 400, Atari 800 and the Atari 2600. Most Sega Master System controllers will function this way with various degrees of success due to the systems sharing the same type of DE-9 control port.

Sord M5 Joystick

A joystick designed for use with the Sord M5 a Japanese home computer launched in 1982. The Sord had two DIN sockets that joysticks could be plugged into.

Philip Harris Easy Memory Unit

Our unit comes with a cable for connecting to a BBC Micro and a temperature probe.

Sound Blaster Audigy 2 NX

The Sound Blaster Audigy 2 NX was an external USB soundcard, supporting 24 bit playback, but with no DSP chip.

Sound Blaster 16 Value Edition

The Sound Blaster 16 was the successor to the Sound Blaster Pro and introduced 16-bit audio sampling to the range of Sound Blaster cards. It was also mostly compatible with software written for Sound Blaster and Sound Blaster Pro cards.

Ours is complete with box, user manual and supporting software.

Sound Blaster OEM Version

Sound Blaster SB2.0 8 bit Sound Card 1991 Reference: CT1350B Rev 4

The Sound Blaster family of sound cards was for many years the de facto standard for audio on the IBM PC compatible system platform, before PC audio became commoditized, and backward-compatibility became less of a feature.

The creator of Sound Blaster is the Singapore-based firm Creative Technology, also known by the name of its United States subsidiary, Creative Labs.

Sound Blaster 2.0 added support for "auto-init" DMA, which assisted in producing a continuous loop of double-buffered sound output and increased the maximum playback rate to 44 kHz (the same maximum as the Sound Blaster Pro, released around the same time). The earlier Sound Blaster 1.0 or 1.5 could be upgraded to support auto-init DMA by replacing the socketed V1.00 DSP with a V2.00 DSP, which was available from Creative Labs.-

Sinclair Instrument Wrist Calculator

The Sinclair Instrument Wrist Calculator was a simple 8-digit calculator, that was only sold as a kit. It was released in February 1977 by Sinclair Instruments, a company ran in parallel with Sinclair Radionics.

It ran off of six mercury batteries, which lasted only about an hour and a half, and required the user to disassemble the unit to change them.

The calculator had a three position button to access extra functions, such as memory and square root. It originally sold for £9.95 (plus VAT). Sales were not great, only around 10,000 were reported sold.

Reliability meant that a great many were returned to Sinclair, as was the case with the Sinclair digital watches.

Powertran Cortex

The Powertran Cybernetics Cortex 16-bit colour computer was a home/business computer that appeared as a construction project in Electronics Today International (ETI) magazine. It was spread over three articles spanning November 1982 through January 1983.

The Cortex began as a design created by some engineers who were working at Texas Instruments UK. Having created the Cortex, they found themselves conflicting with TI's Business and Home Computer divisions, so were unable to make it a commercial success. The solution was to have it published in ETI and have kits (and fully built units) available from Powertran Cybernetics.

The Cortex was sold in a few versions. This model has no disk drives.

Based on the chip of the TI99, it has 64K of memory, and 24Kb of BASIC. There are spaces on the board for controller chips for disk drives, and the BASIC can be overwritten by new languages from floppy disk.

The example in our collections comes with copies of the original articles and its Users Manual.

Irlam Instruments Acorn Replay DIY Capture System

To quote from the manual" The Acorn Replay DIY kit allows anyone to capture colour video and stereo audio at low-cost onto hard disc using standard equipment. Hardware on the expansion card reduces the video and audio bandwidth to allow capture in real-time from ordinary domestic VCRs, camcorders and videodiscs."

"The hardware was designed for the A5000(with standard IDE disc drives) and A540. However the hardware may work successfully on previous Archimedes models providing you have 2MB RAM (4 MB for compression), a fast hard disc and ARM3."

The card can be fitted with an sVHS or S-Video connector fitted. This card does not have either of these connectors (see hole in the backplate between the Audio inputs and composite video connection).

Here is the Acorn Replay DIY capture system manual.

Here is the Acorn Replay DIY capture system application.

It could be used with the Toshiba T1100 and the Toshiba T1200.

Cambridge Z88 All In One Pack

The Cambridge Computer Z88 was an A4-size, lightweight, portable Z80-based computer with a built-in combined word processing/spreadsheet/database application called Pipedream, along with several other apps/utilities, such as a Z80-version of BBC BASIC.

The machine was designed by Sir Clive Sinclair and released by his company Cambridge Computer in 1987 (Sir Clive having been unable to market the computer as the Sinclair Z88 after selling Sinclair Research's computer business to Amstrad in 1986).

The Z88 is a portable computer based on a low-power CMOS version of the popular Z80 microprocessor. It comes with 32 KB of internal pseudo-static RAM and 128 KiB of ROM containing the Operating System (called OZ), but can be expanded up to 3.5 MB of RAM, of which the contents are preserved thanks to the batteries. An integrated capacitor prevents the Z88 from losing its data for a limited amount of time while changing the batteries.

Despite the lightness of the Z88—it weighs 0.9 kg—its construction is surprisingly robust, including its membrane/chiclet keyboard which is both comfortable and almost inaudible (an optional electronic "click" can be turned on if it proves too quiet for the user's taste).

Powered by four AA batteries (giving up to 20 hours of use), the computer has three memory slots; each of which can be used for RAM expansion, removable mass storage, and proprietary program use. Since the slots use RAM, EPROM and ROM for their data transfer, the transfer speeds are usually very high. Although RAM cards of up to 1 MB capacity were available, they were expensive. Most users used one or two 128 KB cards.

Though the SuperTwist LCD display has only eight lines, it is clear and surprisingly effective. In Pipedream, a miniature view of a whole page appears to the right of the display, giving a good feel for the overall layout, and compensating for the inevitable "letterbox" effect.

Our model is in excellent condition with the original box and manual. It is the "All In One Pack" which came boxed with the Z88 computer, a 128k Ram Pack, Mains Adapter, Carry Case, a set of batteries, a 32K Eprom Pack and a Eprom Eraser

Game Boy Color - Teal

The Game Boy Color is a handheld game console manufactured by Nintendo. It was released on October 21, 1998, in Japan, and later released in November of the same year to international markets. It is the successor of the Game Boy. Its successor, the Game Boy Advance, was released in 2001 and the Game Boy Color was discontinued in 2003.

The Game Boy Color was fully backward compatible with older monochrome cartridge. Users could 'colourize' monochrome games by choosing from four predefined palettes.

When released there were five original colours available - the logo for the Game Boy Color spelled out the word "COLOR" in the five original colours in which the unit was manufactured. They were named: Berry (C), Grape (O), Kiwi (L), Dandelion (O) and Teal (R). It was also released in 'Atomic Purple' at the same time, which was made of transparent purple plastic. Other colours were released as limited editions or in specific countries.

Game Boy Color - Atomic Purple

The Game Boy Color was fully backward compatible with older monochrome cartridge. Users could 'colourize' monochrome games by choosing from four predefined palettes.

Psion Series 3A

The Psion 3 range of personal digital assistants were made by Psion PLC. The four main variants are the Psion 3 (1991), the Psion 3a (1993), the Psion 3c (1996), and the Psion 3mx (1998), all sized 165 x 85 x 22 mm. In addition, a Psion 3a variant with factory installed software for the Russian language was called a Psion 3aR, and Acorn Computers sold a rebadged version of the Psion 3 and 3a marketed as the Acorn Pocket Book and Acorn Pocket Book II.

The Psion 3 models were a major advance on the Psion Organiser. They had an original way of managing files: the available program icons are shown in a horizontal line and the associated files drop down beneath them.

Manufacture of Psion 3s was discontinued in 1998 shortly after the launch of the Psion Series 5 (a Psion 4 does not exist, due to Psion's concern of tetraphobia in their Asian markets) and the Psion Siena. Psion's industrial hardware division continue to produce handhelds running the same 16-bit operating system, some 17 years after its introduction on the Psion MC range of laptops and 5 years after Psion Computer's final 32-bit EPOC PDA was released.

Software was available for the PC called PSI Win that allowed the transfer of data to and from the Psion Organiser.

Sinclair ZX81 with Unbranded Case

This ZX81 has been placed inside a kit case which does not have a manufacturers mark. If anyone can help identify it, then please let us know.

It has a plastic top, and a wooden base, and runs off a Euro style plug rather than a ZX81 supply, an equivalent one has been fitted inside the case.

The case has a full travel Maplin keyboard.

It also has an in built 16K RAM expansion, to negate using the original box attached to the rear connector, which suffered from the infamous 'wobble' where a slight knock could wipe the computer memory.

The Maplin kit itself was a full travel keyboard, which connected inside the actual ZX81, which cost £21.95, a moulded case could be added for an extra £4.95.

Maplin could also take your ZX81, and build it into the case for you, at a cost of £29.95.

There are two switches on the back, one appears to invert the black and white, the other is marked H/R, which garbles the screen when switched.
