 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". 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...

 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...

 SHARP MZ 80C
The MZ-80c is based on the MZ-80K, but offers some enhancements to match the professional market of that time. The price was improved too ;-) It was the first MZ-80 computer to be delivered assembled as opposed to first MZ-80k which were sold as kits.
The RAM size is now of 48 KB. The keyboard which was so strange on the MZ-80K because of its matrix organisation, has now a more common layout with a large spacebar key. The numeric keypad is separated.

 RCA Cosmac VIP
The Cosmac VIP, originaly named VP-111, is a typical hobbyist "single-board" computer sold as a kit. You had to build it yourself ! The system uses a RCA CDP-1802 microprocessor like the RCA Studio II video game system. In fact the Studio II is very similar to the VIP and can be considered as its video-game version. But the VIP is also somehow an improved version of the original Cosmac Elf board system, described in Popular Electronics magazine, august 76 an...

 COMPAQ Portable
Announced November 1982, the unit was actually shipped in January of 1983 (300 of them). This was arguably the system that destroyed IBM's monopoly on the PC market and created the situation we see today. It WAS the first compatible system that was LEGALLY made, though Columbia first copied the IBM BIOS and later paid the fatal price.
The system's BIOS was developed from scratch by using a team of 18 persons (only one guy was "dirty" and he was not allowed to do any part of the code and coul...

 OHIO SCIENTIFIC Challenger
In 1977 computing industry is changing fast. Ohio Scientific Instruments who were making a lot of expansion boards for their 400 single-board computer, called "Superboard", realize that it would be nice to sell all this hardware, all assembled, in a single case, ready to plug and use.
That's what is a Challenger computer, more a concept than a single system. Indeed under the name Challenger came different configurations based around the Superboard system:
- Challenger 65-1k: 6502A CPU, ser...

 ATARI 1450 XLD
The Atari 1450 XLD has the same characteristics as the Atari 1400 XL.
Like the 1400 XL, it has a built-in modem (Bell 103 compatible, 300 baud) and the speech synthesiser chip (SC-02). Contrary to the other Atari, it uses a parallel disk drive controller (a much faster arrangement) instead of the SIO interface.
Apparently The 1450 was not released because they were having problems getting the parallel disk drive controller to work properly....

 ORMATU ELECTRIC BV Video Spelcomputer 1001

 OHIO SCIENTIFIC CHALLENGER 4P
When the C4P was launched, Ohio Scientific said that it was a giant step in the world of the home computers. It was twice as fast as an Apple ll or Commodore Pet and more than three times as fast as a Tandy TRS 80.
However, despite its technological lead, the C4P and other Ohio Scientific computers always suffered of a lack in efficient software and attractive handbooks. For this reason, very few third companies built cards and peripherals for the Challenger series. So, the C4P didn't withstand...

 NEC PC 8801
The NEC PC 8801 was the successor of PC 8001. It offered fine colour graphics.
It had an optional MS-Dos board. It was one of the fist, if not the first color CPM computer.
It ran in three bootable modes: CPM, MS-Dos, and N88-Basic. The N-Basic would natively boot on the system without disk, just like the PC 8001. It also had a software / hardware switch to turn it into PC 8001 mode.

 V-MARC 88a
This computer was probably intended for holding OEM programs thanks to its 8 cartridge slots. Cartridges could be ROM, for programs, or RAM to store data.
The internal O.S. allowed for management of these cartridges, running programs or copying data from one cartridge to another. The content of a cartridge could be sent through the serial interface.
The machine could be powered by either an AC adaptor or an internal NiCd battery.
A V-Marc II was also sold with same features but p...

 ACORN COMPUTER BBC Master AIV
In 1986, the 900th Anniversary of the Norman Domesday Book, the BBC and
the National Curriculum, amongst other UK bodies, endeavoured to
produced a 20th Century equivalent. Recently the Domesday project has
had renewed interest, as the sense of producing such an ambitious
undertaking then storing the results on a strange, and now forgotten,
format has been called into question many times since!

interesting - but ...

AM INTERNATIONAL JACQUARD SYSTEMS J100 - J500
I worked for AM Jacquard beginning in 1980 until it was sold to various buyers. Later, I, John Johnston and Karl Hedger found Nor-Cal Data Systems. We would eventually take over Jacquard and Amtext Word processing support and repair throughout Northern California and Nevada. To my knowledge Nor-Cal Data Systems would be one the few companies that sold the follow up Step II product from the Peerless Group. We eventually closed the company in 1990. I have seen many changes over the years. However, I seen very little that has impressed me as much as the Jacquard mini-computers in their prime. Even now, I''m still impressed.

NCR PC4
This computer was my favorite garage sale find of 1995. It even came with it''s own version of DOS, NCR-DOS, and some Peachtree productivity software. But my primary use for this machine was vintage PC gaming. This worked especially well after I installed a used hard card into an available expansion slot. Unfortunately Hurricane Rita tore the roof off the garage where it was stored a decade later, and this machine did not survive being flooded.
