Re: IMSAI haul, continued
- AFAIK, iCOM was the first to advertise an S-100 floppy drive (Byte, Aug '76).
Google reminds me that it was called the "Frugal Floppy". I don't recall any
details, but I think ICOM, Pertec, and Altair had some very close
relationship even before Pertec bought them - maybe they shared an assembly
plant? Altair and ICOM also jointly developed and sold an all-in-one

Interesting, I didn’t realize that ICOM was swept up into Pertec, although it seems to make the world of sense considering the ICOM system I have used the same FD400 drives that the Altair 88-DCDD setup did.

Pertec bought both MITS and ICOM. What did ICOM add to the MITS/S-100
world? And of course pass this info on to Cini. Thanks!
