I was a jr operator on a 4381 in 1991. from what your email says, sounds like
you have quite a lot of hardware to move and setup somewhere. a 3990 control
unit makes me think there are 3880 DASD units which will take up lots of
space and power and make lots of noise to boot. the 4381 is about the size of
a closet and almost 7 feet tall. in the shop i worked in, they had two ac
units going and the standard raised floor. you'll definately need cooling of
some sort. you might try IBM again, call their general number, 800.IBM.3333
or 800.IBM.4YOU (i think) and ask for the number of the local 'branch office'
which should get you some info. I'm estimating you will need at least a 20x20
foot room to run this configuration.
