Having worked with the tahoe (6/32) for 2 years at my previous place of employ,
I can say that its a fast machine, 6 MIPS single processor - hard MIPS (i.e.,
6 times a 780 - for real).  CCI rates the tahoe at 8 MIPS, and the MP
is at 15.  We never got an upgrade to an MP because BSD does NOT run on it.
CCI supports SysVr2 on all their machines, and a very POOR 4.2 port on
the 6/32 *only*.  4.3 is in the works for the tahoe, but not from CCI but
rather from Berkeley, as announced at previous Usenix conventions.  I was
involved in the beta test and the machine I ran is still up on the internet.
CSRG has plans to use the tahoe as their next processor base.

The tahoe is also OEM'd and sold by Unisys (Sperry 7000/40) and Harris (HCX/7).
All earlier products featured a versabus design, which made 3rd party
controllers hard to come by.  While CCI is releasing a new series of
versabus controllers, Harris is now manufacturing the HCX/9, a tahoe
but with a VMSbus for I/O.  Something to watch for!
