Tim Paterson - QDOS and MS-DOS

Tim Paterson has written some articles and appeared in some interviews, as the person who wrote QDOS for Seattle Computer - as a prototype for their new offering, ahead of a planned more substantial multi-user OS.

Digital’s CP/M-86 was in the air, and CP/M, as a proof of concept and as an API, was already popular.

(This is, of course, Tim’s telling of the story, hopefully containing some new and interesting ideas, but not necessarily matching up with everything we’ve read before.)

I came upon some Paterson related history a few days ago. What I didn’t know is that he designed a card that was sold by Microsoft and was apparently Microsoft’s go-to man for bringing software to CP/M. So it was somewhat natural for MS to turn to Paterson’s PC DOS, which he had done for exactly this purpose already.
