I didn't mention the SUN E5500 and E6500 or the Dec AlphaServer 2100 with quad
275MHz 21164's....or some of the other arcane hardware lying around that's
been donated to us (like 1992-vintage Proteon 68020-base Multibus routers;
Cisco's only competition to the AGS line back then).

Whew. As typical, you have thoroughly thought through things. Let me see if
the beast will power up and whether the OS/2 console processor comes up
before we make too many plans, though. And, as I mentioned, it is a SMALL
s390; but it is the genuine article, Model 3006. As I said, a little box.
Its usability will depend entirely upon whether the disks are wiped or not, I
would think; but it does still have the disks, at least. A few 18.2GB units,
IIRC.
If someone would like to donate a midsized 208VAC-capable (single-phase OK,
but has to be 208 and not 240, or at least jumperable) UPS to the effort,
about a 3000VA unit or so, that would help matters considerably! All my good
UPS's are 120VAC at this point (my one good 208VAC unit threw a battery a few
weeks ago; 8 12-270 UPS batteries will blow my equipment budget right now, so
it is off line and the Cisco 12012 router it served is degraded to standby
status on the OC3); while we have a 500KW generator out back, the start delay
would be enough to down the box. Or a 48VDC input 3000VA inverter (a pair of
1500's probably would work) with either a 208 or a 240 output; I have plenty
of -48VDC power.
