Yes, I lust for a S/360 or 370, and would even settle for a 3033 or 3081.
Me too! But I think a 4381, say or even a 9370, would be easier to work
on. Why? The 308X and 3090 (and I think also the 303X, although I know
less about them) were _water cooled_. Maybe I am biassed as an
electrical engineer, but I think that anything with water in it is bound
to make a mess sooner or later...

Getting a 9370 should not be a problem - they are dogs that really were
not sucessful. I have seen quite a few in the scrap yards (none suitable
for taking, however).

Not all are water cooled. Some have air cooled TCMs - very impressive
looking 900 pin PGAs with monster machined aluminum heat sinks. I saw one
at a junkyard once a purchased it for two dollars. I still have it.
