I've sent you details by private email.

Yes, I sure will. I just need to sort out the best way to get a
network connection to it in the garage. There is an ethernet
connection the garage, but in another room to where the workstation
must be mounted (the garage has internal doors). I cant'use ethernet
over the mains wiring, as I have a 3-phase supply and the garage is on
a difrerent phase to the house. I hope to set up a WiFi link. For now,
the HP C3600 is in the house.

Yes.
Many people do not seem to appreciate that by testing on multiple
platforms, you uncover bugs that can affect any platform. Hence it
improves the quality of the software, even if you never ultimately
port to that platform.
In fact, a failure observed on HP-UX caused me to post the contents of
a macro in Sage to the autoconf mailing list. The autoconf guys say
the macro is badly written, and will not even detected the number of
CPUs correctly on all x86 machines.

He was quite prompt at responding to me, but he did say he was going
away at some time, though I forget when it was.
IBM make some machines (p-series) with 5 GHz processors. I suspect
they would run Sage rather well if we ever did get a port to AIX!
I have an IBM RS6000 of my own, but it is rather old, and only 32-
bit.
