Undocumented S-100 boards List

This page last updated June 15 2024, (c) Herb Johnson 2024

To email me, see see my ordering Web page for my email addresses.

This page lists S-100 boards and manufacturers for which I have no documentation. Also, this page names more S-100 manufacturers, and dates their production.If you have documentation or information, please contact me. Check my S-100 Home page for a list of manufacturers that I have docs, or have their own document archives (too many for me to track). But I think my lists account for the most S-100 branded companies.

I have some images of some of these boards, but I don't own those photos, so they aren't shown here. Since I have no documentation by definition, a photo may be the only "doc" I can find. If I have your photo and you object, let me know and I'll apologize and not make the photo available.

To contact me about manuals, to get ordering and price information, follow this link.
