If one (or _anything_) turns up, it's _crucial_ that it be scanned, and the
scans sent to Bitsavers!!! Almost nothing is known of this
historically-important machine - the first thing other than a VAX that BSD
was ported to.


I did a fair amount of scratching around, and starting with the toolchain
(mostly the debugger), which still exists, I was able to retrieve enough to
give us a decent idea of the machine:

There was discussion of trying to create an emulator, from the info in
the toolchain:

  https://gunkies.org/wiki/Talk:Power_6/32

I was able to work out, from the instruction decode stuff in the debugger,
what the instructions look like (fields, etc): but that still doesn't tell
us what all the instructions _do_, at the level of detail that would be needed
for successful emulation. We'd really need that manual!

There is also "Installing and Operating BSD UNIX on the Tahoe", linked from
the above.
