 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 ...

 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...

 DIGITAL EQUIPMENT CORPORATION RAINBOW 100
The Rainbow 100 was a microcomputer introduced by Digital Equipment Corporation (DEC) in 1982. This desktop unit had a monitor similar to the VT220 in a dual-CPU box with both 4 MHz Zilog Z80 and 4.81 MHz Intel 8088 CPUs. The Rainbow 100 was a triple-use machine: VT100 mode (industry standard terminal for interacting with DEC's own VAX), 8-bit CP/M mode (using the Z80), and CP/M-86 or MS-DOS mode using the 8088.
Models
The Rainbow came in three models, the 100A, 100B and 100+. The "...

 HONEYWELL DDP-516
The Series 16 computers were originally designed by Computer Control Company, which was then bought by Honeywell in 1966.
Series 16 computers were used in a wide range of applications. Many were used in computer control applications, and many educational establishments used them as general purpose computers.
The most prominent application of them relates to the origins of the internet. The DDP-516 was used as the basis of "Interface Message Processors" or IMPs that were used to connect t...

 SAITEK Micro Computer (?)
This original computer was to be released by Saitek to rival popular computers of the 80's, mainly the Commodore 64. Designed by Iain Sinclair, it remained a project and was never marketed. The picture you see here is a moulded plastic prototype.
The particularity of this project was to design the available expansions so they can stack up above the computer, from the vertical expansion slot. The project was even called "Wafer Personal Computer".

 POLISTIL V.G. 2
Quite interesting Italian pong system. It is very classic by its functions but very attractive by its cosmetic design.
Indeed the system itself is very common : 4 basic pong games (tennis, football, squash, pelota) in black & white surely driven by the AY-3-8500 chipset from General Instruments.
But the black and electric blue case, with its round shaped angles turns it into a very funky and collectionable pong system....

 MATRA HACHETTE ALICE 90
The Matra Alice 90 is the successor of the unsuccessful Alice 32 and is 100% compatible with this computer. This computer was designed, like its predecessor, to be used as a "first contact" computer.
Genlocking allowed the user to use the computer and watch TV simultaneously.
The ROM contains a version of the world famous Microsoft BASIC, but this version of BASIC can't access to the highest graphic mode (320x250), it could be accessed from the built-in asse...

ELECTRONICA CIP-03
A rather important (but as far as I''m aware, entirely obscure*) feature of the CIP03 was that it still contained a full 64K or RAM, besides the 16K ROM. Clearly, given the 64K address space, only 48K of that RAM remained accessible at runtime - but what most people didn''t seem to realize is that the low 16 of RAM remained accessible FOR WRITING during normal operation, with a D-latch at $I can''t remember which I/O address$ accessible to FLIP that, leaving now the ROM getting accessed for writing (LOL) and the RAM FOR READING, instead of the EPROM. So basically all you had to do was "copy the first 16K onto itself" first, changing whatever you didn''t like about the original BASIC, then flip the latch and bingo you were running your "improved OS".
Which worked wonders for me in fixing the notoriously broken Spectrum NMI vector - now I could run my code any time at the click of a button in a way that was impossible to interfere with in software: basically, a "cheat POKE" user''s wet dream. It was bloody GLORIOUS. Later at some point the same trick worked like magic to transfer code from a CIP03 to an emulator on a PC via a custom, jury-rigged expansion port -$ LPT1 connection: at any point you wished, you pressed the button hooked up to the NMI pin, the CIP froze in place (running my pre-loaded glue code) and transferred the full contents of the upper 48K to a companion Pascal program running on the PC that wrote it into an emulator file$ then you just loaded that file into an emulator, and watched your game un-freeze from the exact spot you stopped it at.
* upon discovery of this "feature", I obviously tried to inquire about it at the local Electronica service. The "WTF"-slash-"huh?" attitude of the staff was utterly priceless.

SANDS 3000
It connects to your TV antenna socket to play 1 of 4 different pong games: tennis, hockey, squash (1 player) and squash (2 players). The player slider control are detachable from the main console. The console runs on 6 C-size batteries, or from a 9V external power supply (not included). I don''t have the UHF cable, but I think it''s just a standard TV aerial cable.
