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
