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.
All that I can find out about them is this table from http://www.dunnington.u-net.com/public/dhrystone.c (archive link)
*----------------DHRYSTONE VERSION 1.0 RESULTS BEGIN-------------------------- * * MACHINE MICROPROCESSOR OPERATING COMPILER DHRYSTONES/SEC. * TYPE SYSTEM NO REG REGS * -------------------------- ------------ ----------- --------------- * CCI POWER 6/32 COS(SV+4.2) cc 7500 7800 * CCI POWER 6/32 POWER 6 UNIX/V cc 8236 8498 * CCI POWER 6/32 4.2 Rel. 1.2b cc 8963 9544 * VAX 11/780 - UNIX 5.2 cc 1515 1562 * VAX 11/780 - UNIX 4.3bsd cc 1646 1662
Which may give some indication on the initial reasons why the Power 6/32 was chosen as the sucessor to the VAX by CSRG.
