Seattle Computer Products was a manufacturer of S-100 boards and systems. 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 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 and sold to IBM for their new IBM-PC, as MS-DOS and PC-DOS respectively. A Web search for "Seattle Computer Products" will find many sites which discuss this history.
