 ECD CORPORATION Micromind
The Micromind was a very innovative machine ahead of its time ! But despite the small group working on the machine, prototyping and developing, and pushing the limits of the time, the machine never shipped. Apparently only a few prototypes were produced.
Development began as early 1975/1976 but commercial adverts appeared only in 1977.
One of the main features of the Micromind was its innovative (for the time) redefinable characters. Up to 120 characters could be software redefined by the ...

 LOGICAL MACHINE CORPORATION (LOMAC) Tina
The Adam was the first computer released by Logical Machine Corporation (LOMAC) in 1976. In 1978 they produced Tina which stands for "TINy Adam".

 GESPAC Gescomp 720 / 730
GESPAC SA was a Swiss company who designed the G-64/96 Bus in 1979.
This interface bus concept provides a simple way to interface microprocessor modules with memory and peripheral modules on a parallel bus. The G-64/96 Bus uses a simple, yet modern and powerful interface scheme which allows a higher level of functionality from the single height Eurocard form factor. The low overhead of the G-64/96 Bus interface greatly eases the design of custom boards by the User. This is why, even many year...

 WELECT W86
The W86 is a french computer released in 1983 by Welect. It's the second computer released by Welect after the W80.2.
The W86 is powered by an Intel 8086 (hence its name) to catch up with the IBM PC compatible trend of the moment and is thus able to run MS-DOS. But the W86 is also equipped with a Z80A to also be CP/M 86 compatible. It's thus an hybrid machine typical of the mid-80s when the professional industry was moving from CP/M to MS-DOS.
There are 128...

 ACORN COMPUTER Archimedes A4000
The Acorn A4000 was a slightly cheaper cut down A5000, with a shorter case, one expansion slot and an ARM250 processor.
Curiously, the machine had its floppy and hard drive fixed to the chassis with a wire clip which meant these could be quickly replaced without tools, whereas replacing the hard disk on the A5000 was a more fiddly operation requiring the expansion slot plane and the whole chassis holding the drives to be removed.
Many of the features (ARM...

 OSBORNE CORP. OSBORNE 1
The Osborne 1 is one of the first portable computers but needs external power source. Its name comes from Adam Osborne, the man who made this computer a reality (not quite true, see end of the text).
It has a very small built-in screen (8.75 x 6.6 cm, which can display 128 columns!!) and weighs more than 10 Kg.
The first models couldn't display more than 52 columns by line, so to access to the 76 other columns, the user had to scroll among the screen thanks to the cursor keys.
It works un...

The Apple II+ was the successor to the Apple II.
It was fully compatible with the Apple II. It, however, had new features:
- a new ROM holding the AppleSoft Basic (floating point version written by Microsoft),
- a new auto-start (stored in ROM) for easier start-up and screen editing,
- 48 KB RAM,
- text modes were the same as the Apple II, but the graphics modes were enhanced, they're the same as the Apple 2e : 16 colours at low resolution and 6 colours a...

 DIDAKTIK Gama
This was a Slovak Spectrum clone made by Didaktik Skalica Ltd. in communism times (1987). It offered 80 KB RAM.
As all Z80A based computers, it was not possible to address more than 64k. So the Gama computers used a bank switching technique, with two 32k additional RAMs. There was even a LED on the case, which indicated if the RAM have been switched or not!
The Gama computers had a built-in paralel i8255 interface. They used the original Ferranti...

 MYARC Geneve 9640
In 1983, Texas Instruments announced the cancellation of the 99/4A Home Computer. This was shortly after they announced their intention to produce its successor, the TI-99/8, a computer with the "big brother" to the 4A's TMS9900 processor, the TMS9995.
Myarc was a company that made a name for itself selling expansion cards for the TI's Peripheral Expansion Box, including memory, RS232, and disk controller cards. They also produced a "replacement" for the large PE Box in a smaller self-conta...

Can anyone please let me know what this component is?

DIGITAL EQUIPMENT CORPORATION 300 Professional series
The 300 Professional Series was, in truth, only "sort of" compatible with most of the PDP-11 line. Radically different interrupt hardware, and many other vital differences, meant that even the operating systems needed major modifications to work. Almost none of the software from the PDP-11 could run "as is". This left you what seemed like a fine machine with almost no software. For all of IBM''s faults they did a far better job here. Other things prevented this model series from catching on.

ALTOS COMPUTER SYSTEMS ACS-586 / 686
This was the best machine to run a multiuser bulletin board. From 1988 until around 1992 I used one to run UNCENSORED! BBS using the Citadel software (see the link above $ it''s still running today on Linux). The fact that the Xenix operating system handled all of the serial and modem stuff for you made it an excellent choice for any multiuser system.

DYNALOGIC HYPERION
Stumbled across this site, as I was just thinking about the good old days at Dynalogic/ Hyperion. I used fly out of Canada every 2nd week to train dealers on how to repair the machines. It got so bad, that I ended up writing a piece of software that we later sold to dealers (I think Dysan ended up copying it and selling it under another name, my first experience with such business practices). My software allowed them to use the machine as a disk drive exerciser alignment tool (yes, because the drives caused the machine to be DOA far too many times). I later switched over to a company that made a solid state disk drive emulator (for the Hyperion), using "bubble memory" - it too had technology failure problems LOL. Those were the days. I still have a brand new Hyperion, in the original bag, with all the various software. BTW, we called it a "luggable" back then.
