Toshiba T3200 SXC

Toshiba T3200 SXC

Toshiba said in 1987
"Toshiba knows that in the PC world bigger isn't always better. And Toshiba proves it again with the Toshiba T3200. The Spacesaver. A fast portable with expansion slots. Full size keyboard. Separate numeric keypad. Mobility.

Power. Capacity. Speed. Full size desktop function in an elegant and compact package. And speed has never looked so beautiful. Inside the portable T3200 is a powerful, fast, and expandable full function computer. Not only a high speed 12 MHz 80286 microprocessor but also a fast 40 MB hard disk. And EGA graphics as standard. A high resolution variable contrast gas plasma display and optional memory expansion to 4 Megabytes - without using a slot. The full size keyboard has a separate numeric keypad. Two expansion slots are standard. Fit a network card. A bus mouse. Mainframe communications. Graphics processor. Or a modem. Or any other expansion board from a wide range. And the complete computer can always be folded and locked away to provide the complete security that desktops lack.

The Toshiba T3200. The Spacesaver. Another wonder from Toshiba."

Our other 3200 has the red plasma screen, this is the full colour version.

Jupiter Ace in replacement Camputers Lynx Case

Jupiter Ace in replacement Camputers Lynx Case

The Jupiter ACE was a British home computer of the 1980s, marketed by a company named Jupiter Cantab. The company was formed by Richard Altwasser and Stephen Vickers, who had been on the design team for the Sinclair ZX Spectrum.

The Jupiter ACE somewhat resembled a ZX81 in a white case, with black rubber keys like the Spectrum. It displayed output on a television, and programs could be saved and loaded on cassette tape, as was standard at that time. The machine came with 3 KB RAM, expandable to 49 K. It had its own RAM packs, which are very rare and fetch high prices, however a ZX81 Pack can be used with an adaptor.

The owner of this ACE has replaced the original case with one belonging to a Camputers Lynx. The extra space within the replacement has enabled the power supply to be incorporated and can be seen in the top right of the second image.

Acorn 32K Dynamic Ram Card

Acorn 32K Dynamic Ram Card

The Acorn 32K Dynamic RAM card is a Eurocard which can be used in a System or Atom computer.

The card provides up to 32K of RAM for a computer using Acorn's standard data bus. The ICs used are 5v 16k bit dynamic RAMs organised as 2 banks of 16K. Timing is generated in synchronisation with the CPU clock and the hardware refresh circuitry allows random access of the memory in any clock cycle. The RAM is organised into 4 sections each of which is 8K. These 4 sections can each be linked to begin at addresses 0, 2000, 4000, 6000, 8000, C000 and E000. In Acorn Systems 2, 3 and 4 the card will usually be used to provide 8K of program space at C000 to DFFF and 24K of text space at 2000 to 7FFF. A 16K card can then be used to fill the remaining space from 8000 to BFFF. Acorn Dynamic RAM cards can be mixed with static RAM cards and can be paged if required.

 
Acorn 8K Static Ram Card

DECMate III

DECMate III

Costing around $7000 dollars on release, This computer was the last machine based on the PDP-8 architecture, the computer offers less expansion capabilities than the DEC Mate II, which also made it considerably cheaper.

There is a single chip on board that contains all the PDP 8 hardware.

The machine has two 5.25 drives on board, and in part due to its small size there is no way to connect a hard disk, however the machine does support a colour monitor, which could replace the standard monochrome model.

Aimed at the word processing market, the computer could also run other applications such as OS/278

A year later a new model, the DECMate III+ was sold with a hard disk controller, and new hardware, fully compatible with its predecessors.

Philips CD-i 490

Philips CD-i 490

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.

The CD-i player 400 series, which includes the 450, 470, 490 models. The 400 models are slimmed-down units aimed at console and educational markets. The CD-i 450 player, for instance, is a budget model designed to compete with game consoles. In this version, an infrared remote controller is not standard.

The CDi 490 is a good model to own, as it has the Digital Video Cartridge built in, it is a slightly more enhanced version of the CDi 470, aimed more at he institutional end of the market, the machine has 32KB of internal ROM.

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.[2] The first Philips CD-i player, released in 1991 and initially priced around USD $700,[3] 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. The CD-i proved to be a commercial failure in that market segment and some of its games have claimed to be among the worst games ever made. Philips ceased publishing video games for the platform in 1998.

The model number is CDi 490/00. It was made in Belgium and has a production number of AH019828010012.

 
Philips CD-i 210/45

Philips CD-i 210/45

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" (Pictured) to provide MPEG-1 decoding, as do some of the machineís better games, this additional cost made the machine prohibitively expensive compared to rival systems, such as the Snes and Megadrive.

 

The CD-i proved to be a commercial failure in that market segment and some of its games have been known to be among the worst ever made. Philips ceased publishing video games for the platform in 1998.


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

The Cdi 210 series are a slightly cut down version of the CDi 220, with a less sophisticated front panel display, and a cheaper CD tray and loading mechanism.

There are even different models in the 210 series, with the 210/25 using the    22ER9141/00 DVC cart rear loading cart, and this 210/45, which has the GUI from the 400 series and an internally fitted 33ER9956 DVC cart.

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.

Apple IIc Flat Panel Display

Apple IIc Flat Panel Display

Portable screen that attaches to the rear of an Apple IIc.

The screen itself is monochrome, and does not have the greatest viewing angle. It is not very common, mainly due to the parent machine the Apple IIc not being a big seller. Apple had hoped to sell 100,000 a month of the portable machine, they only managed that in a year, for roughly four years, and even the IBM PC Jr, itself a sales disaster, outsold it in the first year on sale.

The screen had an impressive 560x192 resolution, and connected via a DB-15 connector. One of the main faults with the machine was the lack of a back light.

Not being actually fixed to the Apple computer was seen as another drawback, as it could relatively easily slide off, only being held in place by a small slot on the computer.

Also it could only really sit at one angle which made it unsuitable for smaller users. The screen would soon find itself superseded by others that cured these faults.

Less than 10,000 were made, and these initially retailed for $600.

Its rarity, and unusual design make it quite a collectors piece among Apple aficionados.

Care Electronics 4 ROM cartridge

Care Electronics 4 ROM cartridge

The care Electronics 4 ROM cartridge was designed for use with the BBC Master, the cartridge fits in the 2 slots above the keyboard. Each cartridge slot could support 2 ROMs, however the cartridges can hold 4 ROMs and allows you to switch between the 2 ROMs on the left and also the 2 ROMs on the right using the switches on the top of the cartridge. This allowed double the number of ROMs without having to change cartridges or remove ROMs from the cartridge to insert new ROMs.

Atomwide 8Mb RAM Upgrade (1991)

Atomwide 8Mb RAM Upgrade (1991)

The Atomwide A5000 8Mb Ram upgrade can upgrade an A5000 from 2MB to 8MB. This card only has 2MB in 16 x GM71C4256AZ-70 RAM (= 16 x 256k x 4 = 2MB) and is also missing components on the right. The card fits on the A5000 memory expansion.

To address a further 4 MB a second MEMC1a is required. On this card the MEMC1a on the motherboard is removed and a plug on the bottom of the card would fit its socket, the MEMC1a is then added to a socket on the top of this card. An second, slave, MEMC1a is installed on the card with the additional 4 MB RAM.

This multi function device, when plugged into a ZX Spectrum or ZX81, eliminates the need to swap plugs when loading or saving data. A built in speaker acts as an amplifier to boost the sound output from a ZX Spectrum. A selector switch on the front of the device switches between Save, Load and Amp modes. Originally released in 1983 the controller retailed for £14.95. 

 
Archimedes Filtered Sound Output Card

Archimedes Filtered Sound Output Card

The Archimedes Filtered Sound Output card is suitable for Archimedes (A300, A400 & A400/1) and A5000. The internal sound on the Archimedes (and A5000) was quite good, but if the headphone socket was connected to an external hi-fi system then all sorts of interference becomes apparent. The card is designed to fit on the internal sound header plug on the motherboard and generate a clean audio output free from interference. 

 
CCS 4MB A5000 RAM Expansion

CCS 4MB A5000 RAM Expansion

 The CCS A5000 4MB RAM Upgrade has 4 x HM514260JP8 RAM chips giving 4 x 256Kb x 16 = 2MB.

 
IFEL A5000 2MB RAM Upgrade (issue 1)

IFEL A5000 2MB RAM Upgrade (issue 1)

The A5000 came with either 1MB or 2MB RAM on the motherboard and a 1MB model could be upgraded to 2 MB by adding RAM on the motherboard. But the A5000, like all MEMC1 based computers, could address 4MB, so 2MB RAM upgrades were produced by Acorn and third parties to add 2MB RAM for a maximum 4MB. Actually some companies produced upgrades to 8MB using a second MEMC1. 

This is the 1995 M520 issue 1 upgrade.

Irlam Instruments Moving i-Mage

Irlam Instruments Moving i-Mage

Irlam Instruments described Moving i-Mage as:

Moving i-Mage is the first high performance video digitiser to bypass the standard Archimedes display hardware. This allows full motion video, with millions of colours, to be scaled into a window on the desktop. Moving i-Mage can display live video in any RISC OS screen mode, whilst scaling and cropping the video in real-time. Hardware is used to update the window leaving the processor free to carry out other tasks. Features include a single width expansion card and expanable system using removeable digitising modules to support existing and future video formats. Fields and Frames can be frozen and turned into high-quality sprites. Resolution, scaling and cropping of input video is fully programmable. Up to 1024 by 512 lines can be stored in the video memory. In practice the largest single image possible will be 720 pixels by 512 lines within the framestore, whilst a still image can be digitised up to 768 by 576 lines. brightness, contrast, saturation, hue and colour balance can be controlled.

 This Moving i-Mage card has a SVHS 4:1:1 digitiser.


 
Commodore Super Pet

Commodore Super Pet

The Commodore SuperPET also known as the SP9000, was developed with the University of Waterloo of Ontario Canada.

It runs on two processors, the MOS 6502, and the Motorola 6809, which can both access the same addresses, but are independant of the Kernal ROM.

The machine has the basic ROM 4.0, 96kb of RAM, and originally retailed for $2000.

Aimed at the University and programming communities, the machine carried a true RS232 interface, allowing academics and developers to upload their work at home to an IBM mainframe.

The computer starts with a menu of powerful programs for machine language, APL development package, basic development, text editor, fortran and pascal.


 
Vega +

Vega +

This was a crowdfunded project through Indigogo, by Retro Computers Ltd, to produce a hand held console, which was a follow up to the ZX Spectrum Vega, which had been shipped previously to backers and retail.

Trouble was soon to hit the project when two of the directors quit the project, but not the company, when a disagreement about another project surfaced.

After years of delays and legal arguments and cases, that are too numerous to go into here, the company finally delivered just around 40 of the 4772 promised machines and then no more. This was after a threat from Indigogo to send it a debt collection agency to recover the money.

Repeated requests for refunds were ignored, very few of the thousands of backers were to see their money returned.

The machines released are functional at best, and clearly unfinished, with terribly stiff controls, and surprisingly sharp edges, and only a few games installed, extra games are supposed to load from the SD slot, but fail to do so, and may not have the firmware installed to do so.

This is one of the most infamous crowdfunded projects certainly in the computer world for the sheer amount of money raised and so little delivered, and for the amount of hateful posts the subject gained online.

On 5th February 2019 Retro Computers were wound up by the high court, no more units or money have been returned to backers, the page on Indigogo simply says closed.
