Thanks. I'm thinking we could classify the Unix clones under three categories:
the commercial, such as UniFlex, Idris, UNOS
the academic, such as Minix and Tunix
and the hobbyist such as Linux at its beginning
Then it strikes me that that could probably apply to Unix at various stages in
its history:
v1, v2, v3 hobbyist v4?
v5, v6, *BSD academic
SysIII, SysV commercial

Idris from Whitesmiths once passed through my hands...
I actually
skipped that one for UniPlus SysIII and SysV on the
Perkin-Elmer 7350 box with a dip packaged 68000...
I ran Coherent until I got the hardware to go 386-BSD, NetBSD, FreeBSD,
and Linux 0.99.xx (SLS and later Slackware).
Before the UniPlus I ran Xenix-86 on an AT&T 6300 with a Nec V30 (not a
6300+ 286 box).
