Hello. A week ago I asked which machines used which form of UNIX.
Thanks to the people who responded. The following is a summary (of
sorts) of the information I've received. If there are mistakes or
inaccuracies, please email me. Thanks.
-----------------------------------
The underlying fact is that, since BSD is derived from AT&T, the
differences should more properly be addressed as machines using BSD
and System V. Many implementations are based on System V but have
"BSD enhancements". Many kernels are based on one flavour, yet the
libraries may include stuff from both BSD and System V. Having said
that, the following table is separated into the two categories based
on what it consists "most" of. The lists are in no particular order.
BSD System V
--- --------
Sun (SunOS) (lots of SysV) AT&T 3B's/7300
Data General AT&T (leaning towards BSD)
HP (HP/UX) IBM PC's (Coherent)
Apollo (HP-owned) IBM PS/2, RS6000, et al (AIX)
Minix IBM PC's (SCO Unix & SCO Xenix)
Vaxen (BSD4.3) Stratus
Solbourne Bull
DECstations (Ultrix) Sequoia (Topix)
NeXTs PC's (MicroPort)
Sony News stations A/UX 2.0 (with lots of BSD)
Sequent (Dynix) Sequent (PTX) ??
Motorola NCR
Pyramid Prime
Sequoia Convergent (Intel and Motorola)
Data General IN2/Seimens/Nixdorf
CCI/ICL
NEC
Mips (mix) Concurrent RTU (real time unix)
Encore (uses both)
Arix (was Arete)
Olivetti
386-s: SCO, AT&T, Interactive, ESIX
