 NETRONICS Elf II
The Netronics ELF II was an early microcomputer trainer kit featuring the RCA 1802 microprocessor, 256 bytes of RAM, DMA-based bitmap graphics, hexadecimal keypad, two digit hexadecimal LED display, a single "Q" LED, and 5 expansion slots. The system was developed and sold by Netronics Research and Development Limited in New Milford, CT, USA.
Unlike similar "bare circuit card" trainer/experimenter computers of the day, the ELF II could be easily expanded thanks to its built-in bus.

 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 ...

 SEMI-TECH (STM) PC
This extremely rare computer is Portable PC (IBM compatible) conceived in the same plastic case as the Pied Piper, released by the same company in 1983. This computer incorporates a lot of features in a compact case, which was quite innovative at the time: built-in LCD display, printer, modem, phone and disk drives !
The STM PC is based on an Intel 80186 processor and two quadruple-density disk drives. The processor is faster than the one used in the IBM PC, a...

 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". It seems to have the same specs as David but with two 8'' floppy disk drives. There was also the Goliath, a data storage server with 5MB hard drive. Goliath could be connected to up to 20 Davids or Tinas. David and Goliath names makes a clear reference to the mythical story found in the biblical Book of S...

 LOGICAL MACHINE CORPORATION (LOMAC) L-XT
The L-XT was the last computer released by Logical Business Machines, after the Adam, the David, the Tina and the Goliath in 1982. It was announced at the 1983 COMDEX Fall in Las Vegas, and commercially available in March 1984.
The L-XT uses a 16-bit Intel 8088 CPU with 192KB RAM, and equipped with a 5.25'' floppy drive unit (320 KB capacity) and a 10 MB hard disk (upgradable to 60 MB)...

 LOGICAL MACHINE CORPORATION (LOMAC) David
The David is not the first computer released by Logical Business Machines. In 1974, LOMAC (Logical Machine Corporation) released the Adam. Some times later they also produced Tina (for TINy Adam). There was also the Goliath, a data storage server with 5MB hard drive. Goliath could be connected to up to 20 Davids or Tinas. David and Goliath names makes a clear reference to the mythical story found in the biblical Book of Samuel.
The David is powered by a 16-bit Intel 8086 CPU w...

 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...

 SEGA Genesis 2
The Genesis 2 is basically just a redesigned Genesis.
The Genesis 2 was much smaller and squarer then the original Genesis. It did not have the headphone jack, volume control or RF TV output. The A/V port changed to a custom multi out port that now provided stereo sound to T.V's (previously only mono was output by the Genesis, the headphone jack had to be used for stereo sound). The power lead port was made smaller and a different AC adapter was used. Fi...

 WORLDS OF WONDER Action Max
Action Max from Worlds of Wonder (WoW), released in the US in 1987, was a unique, if simple and ultimately unimpressive game system that used special pre-recorded VHS video tapes for software. The original package came bundled with the base unit, light gun, television sensor, headphones, connection cables, documentation and one game, "Sonic Fury". Batteries or a power supply were not included. After connecting the components to the base unit and the base unit to any standard VCR, the player i...

 UNISYS Icon
The ICON workstation and LEXICON file server were originally designed by Cemcorp, the Canadian Educational Microprocessor Corporation, specifically for use in Canadian schools. They were first produced by Burroughs then took the name of Unisys when Burrough and Sperry merged to form Unisys.
Up to about 20 diskless workstations got everything off of the central file-server. They ran QNX, a flavour of Unix operating system with optional GUI shell. The ...

 FUJITSU FM 11 AD 2
The FM-11 AD2 is an evolution of the FM-11 AD. It is delivered with the OS-9 operating system.
There was also a FM-11 AD2+ model with enhanced features like 256 KB RAM instead of 128 KB.
Torsten Dittel, from Germany, adds:
Looks like the FM11 AD2 had an HD63C09EP from Hitachi installed. It was a
PIN/Code compatible CMOS/3MHz version of the MC68B09E from Motorola. For licensing reasons Hitachi kept as a "secret" that it...

 MICROACE MicroAce
A few months after Sinclair released its ZX-80, Microace of Santa Ana, California launched a clone of this computer.
It was exactly the same machine, but a minor modification made that it could be expanded to 2 KB of RAM.
The internal ROM was also a pure copy of the Sinclair's original. Sinclair thus sued Microace but met with large difficulties because the judge couldn't seee the ROM content!
Sinclair eventually won because the Microace keyboard was also iden...

 ACT Apricot Xi
The Xi was the hard-disk version of the cream-coloured Apricot PC.
The keyboard could be clipped to the underside of the machine, and a little cover would slide over the front panel to conceal the floppy drive. A handle then slid out of the front (just under the ridge) that allowed it to be carried very easily.
A colour screen was available - a re-packaged 10" Sony Trinitron screen that almost nobody bought because it was so expensive.
The mono screens h...

 MATRA MAX 90
Like the MAX 20, the MAX 90 was derived from the AX 25, a computer designed by Axel, a small and innovative French company.
It was an almost PC-compatible system including some rare features at that time: 8 MHz 8088 processor, high resolution capability, and especially one or two 5.25" floppy disk drives of 2.7 MB capacity each. To our knowledge, it's the highest capacity ever seen for a 5.25" floppy drive unit.

 PALLADIUM Video-Computer-Game
The Palladium Video-Computer-Game is one of the many systems "software-compatible" with the Emerson Arcadia 2001.
Though, the Emerson Arcadia 2001 is the most popular system of this console group, it was not necessarily at the origin of it. Things must be seen differently. Philips / Signetics developped a hardware platform to demonstrate the possibilities of their Signetics 2650 & 2636 chipsets. Somehow, this hardware was licenced (by Philips?) to many th...

 ONTEL OP-1
About Ontel OP-1 systems and Ontel company, Bob Hanrahan sent us this testimony:
Memories of Ontel, Woodbury NY
I worked for Ontel Corporation from 1979 to 1982, designing various controller boards for their line of 8008/8080/8085 based computer terminals.
The OP-1 computer family included their high end 64K DRAM system called the OP-1/64. The OP-1/64 had a 10 card backplane (similar to VME) allowing it to be configured as a terminal, wo...

 MICRODIGITAL TK-85
After the TK80, TK82 and TK83 the TK85 was the last ZX-81 compatible machine Microdigital produced.
However it wasn't only a simple copy of the ZX-81 but featured several useful enhancements. Its rubber keyboard and case were similar to the Spectrum's and were much more pactical for intensive use. The 10 KB ROM held an improved version of the Sinclair's Basic with strings management and editing facility, as well a...

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.
