Mei culpa/my apologies -- I left out the ISC part of the story and I was
not trying to rewrite history in any way. In fact, to the rest of the
list, ISC did the first 386 port of UNIX - which for UNIX history is
extremely significant. One of my favorite pieces of salesmanship - Heinz,
Peter, and Phil Shevrin managed to convince both AT&T and Intel to
separately pay for the 386 port (and I thought IBM was in that mix somehow
too). Then ISC brought it out as a separate product that I think Sun ended
up with at some later time yet. If I recall, ISC did the original work on
the RT (which redates the RS/6000) and the ISC folks had their own product
for VM before IBM released AIX/370 as a product. Heinz and Charlie would
know more details on those ports.
That said, the comment that I was originally replying to was about IBM
getting interested in BSD UNIX and my point was simply, AIX/370 was
BSD-based and was shipping as an *IBM produc*t years before Linus even
started working on what would become Linux for his 386 based machine; much
less any attempt to get it running on the 370.
Also, if we are to be complete. Tom Lyons did the original 360/370 C/UNIX
work at Princeton & AT&T long before any of that, starting in the mid-1970s
but I'll let Tom fill you in there.
