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 are 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.
