The Power 6/32, code named Tahoe, from Computer Consoles Incorporated, was the CPU for a supermini; the CSRG ported 4.3 BSD to it, in the '4.3 BSD Tahoe' release.
Although it was not very successful commercially (in part because CCI exited the computer business shortly after it was released), it was very influential as the first non-VAX machine that BSD UNIX was ported to. The Tahoe did help separate out a lot of VAX-specific code from the base, allowing BSD to become more portable, but the Power 6/32 machine quickly disappeared off the market, and not much is known about them.
It was re-sold (under other names) by several vendors: Unisys sold the 6/32 under the name 'Unisys 7000/40', using their own bastardized BSD+SYSV Unix. (Kuwait Petroleum in Denmark had one of them.) ICL had the 'Clan 7'. Harris had the HCX-5, -7, and -9 models (for which a bit survives - below), running the SysV derivative HCX/UX.
Pixar used a Power 6/32 to render the stained-glass knight in the 1985 movie Young Sherlock Holmes.
Details
The Power 6/32 CPU was implemented in TTL; it had a clock rate of 100nS.

Which may give some indication on the initial reasons why the Power 6/32 was chosen as the successor to the VAX by CSRG.
