The Tahoe was the code name for the Power 6/32 from Computer Consoles Incorporated that the CSRG had ported 4.3 BSD to in the 4.3 BSD Tahoe release.
Although the Tahoe did help separate out a lot of VAX specific code from the base, allowing BSD to become more portable, the Power 6/32 machine quickly disappeared off the market, and not much is known about them.
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. Harris had the HCX-5, 7, and 9 models, running the SysV derivative HCX/UX. ICL had the Clan 7.

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