Didn't everything except the 93xx series need special power supplies and
airconditioning? The 43xx series weren't water cooled from what I
remember but all the ones I ever saw were in computer rooms, in
temperature controlled environments and bolted down to the floor with
massive cables running to them. The 93xx (did I get that model number
right) were the ones that IBM advertised as being suitable for branch
offices and didnt need anything particularly special.

I think a 43xx series would cost you an arm and a leg in electricity
bills too :-)

Ah yes, the good old Power/Coolant Distribution Unit (PCDU),
Motor-Generator (MG) sets, glycol - with chillers on the roof, scads of
20 ton air conditioners, all on a raised floor. And who can forget the
infamous Halon fire suppression systems!

Those were the days my friend.


That and a freight elevator or a crane to get some of the equipment into
your building. ;-)

One place I worked had a 4341 salvaged from their old configuration
and kept around for backup purposes after the 3090 was installed. It
was about the size of large office desk. Even the 4381 wasn't an
extremely large unit.

43xx were air cooled. 4341 was in the middle of the range and required
external control units as well as the I/O. Expensive to run with high
software and environment cost, but nothing like the 308x type system. No
special power supply (3 phase) and modest aircon.

I've never worked with the 43xx series, but I have seen a few. That's
exactly what they reminded me of - a large desk. I bet that the
electricity costs would still run you an arm and a leg. That, and I
doubt that your neighbours would be too happy if you ran one out of your
home. They probably generate an awful lot of RFI.
