Yes, that was my recollection from things we heard at Tandem.  We were
just getting on the System V bandwagon ourselves, and we looked at Sun
with great suspicion.

No, I don't think so.  My recollection at the time was that
Intel-based UNIX was looked on as something of a toy.  When we *did*
start using UNIX on Intel, it was In(ter)active UNIX, not SCO, which
we looked upon as a strange hybrid with Microsoft.

Yes, I think this is quite valid.  At the time we also used some of
the "Berkeley extensions" like TCP/IP.  Others include FFS in the list
of extensions, though we didn't implement it.  The impression I got at
the time was that BSD UNIX was pretty crappy, though it contained some
good ideas.  It wasn't until I actually got my hands on it (BSD/386,
in March 1992) that I was surprised to find how much better it worked
than Interactive UNIX/386.
