This page last updated July 25 2008. Here is how to order S-100 stuff and email @ me. My S-100 home page of docs and information is at this Web link.
Seattle Computer Products was a manufacturer of S-100 boards and systems. SCP produced a number of S-100 memory cards, such as a series of 16Kbyte cards. Here's a 1978-designed SCP-16K card, produced in mid 1980. Here's a 1979-designed Apex model card by SCP, produced in 1980. Here's a 1980 Apex2 SCP card.
They developed an 8086 based S-100 system in 1979, but Digital Research did not have a CP/M for the 8086 at the time. So in 1980 a SCP programmer named Tim Patterson developed for them an operating system based on features of CP/M and called it "86-DOS". This OS was licenced (and eventually bought outright) by Microsoft in 1980-81; Microsoft licensed it to IBM for their new IBM-PC, as PC-DOS while selling it themselves as MS-DOS.
We have more discussion about S-100 companies which adopted the 8086 and 8088 on this linked Web page. But I leave fine details, and fights about them, to the many other Web sites, articles and books which discuss the development of the IBM PC.
SCP continued to sell MS-DOS with hardware systems for some time after the IBM PC. Again, because of the MS-DOS connection, the history of the company, and Tim Patterson, is available on other Web sites, articles, publications, etc.
