Power 6/32

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.

All that I can find out about them is this table from [https://web.archive.org/web/20150123191735/http://www.dunnington.u-net.com/public/dhrystone.c http://www.dunnington.u-net.com/public/dhrystone.c] (archive link)

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