S-100 Boards
This section of this web site is dedicated to the description of S-100 bus boards. Probably as many as 1000 different types of these S100 boards were sold starting in 1976 and running into the mid 1980's. The history of these boards is reflected in the history of the companies that made them. This section of the web site will be dedicated to collecting and storing information about these boards. It will be an almost never ending and time consuming process. Boards are grouped by the company that manufactured them. I will try and mention a common format. There are numerous descriptions of S-100 boards on the web. Some of these invaluable sites are listed here. However what is really need is one central location where one can obtain quick and detailed information. I will over time try and achieve this. Contributions by others here would really be appreciated. If you have a high resolution picture of a board (or ones better than I have here) I will be delighted to post them here.

Also any manuals missing, information, corrections etc. please let me know so we can really help our fellow hobbyists. Boards with manuals/documentation are shown in Cyan. Boards missing manuals are shown below in Green.  Boards in Grey are those I have too little information at this time to present. To reach me send an e-mail (see bottom of home page). 

Please see here for acknowledgements of help from many generous people that made this table possible.

Performics Inc.  They were located in Kingston & Nashua NH. They had a number of interesting S-100 boards around 1984. These included a 256K static RAM board, a FDC board, a 1M Dynamic RAM board an 8086 and 80286 CPU board. See for example Microsystems 1984,  Vol5, #9, p 104.
Memory Merchant. They were located in San Leandro, CA. They made 16K (using 2114's) and 64K (using 6516's) Static RAM boards, a Z80 board and possibly others.  See for example Microsystems Feb 1983, Vol 4, #2, p38.
Octagon. They were located in San Jose, CA. They appeared in the mid 80's with complete 8 &16 bit S-100 bus systems in their own custom box. They had an NSC-800 (Z80 compatible)/8088 dual CPU board, a 512K dynamic RAM board and a 256K static RAM board. They also had a FCD and HDC board. See Microsystems 1984, Vol 5, #1, p130
Sierra Data Sciences.  They were located in Fresno, CA. They appeared in the early 80's. They had a Z80 SBC master and slave board and a 4 port serial board. See Microsystems 1982, Vol 3, #4, p1. For a history of SDS see here.
Earth Computers.  They were located in Fountain Valley, CA. They came late into the game but had some good SBC boards. For example a "Turbomaster 8" with a Z80H at 8MHZ, FDC,DHC,256K RAM etc. on one board. See S-100 journal, Spring 1986, Vol1, #3 p9. See here for more information about teh company.
SKI Elecronics. They were located in San Jose CA. They made a 8088 CPU board that was IEEE-696 compatable. All I have so far is an advertisement. See here.
