Could it be that IBM did not sell many or none at all in UK? They were
first sold in '86/'87 until about 1990 or '91 I think.

I'll check deeper into this at work, however, if any IBM folks out there
could tell me how to confirm this, I would like to hear from you! :^)

I could not drag home all of the peripheral units (the comm. controller,
3262 printer (S/370 Bus), and other incidentals) No room for it all :-(
Sorry folks, it was only a partial rescue.

I meant help by email of course :^) Thanks for the offer of help! Though,
if you're ever in the neighborhood... ;-)

Maybe through use of email, snail mail and even 'phone/fax, you and anybody
else who's willing to pitch in to help me solve the startup problem(s) are
absolutely welcome to jump in whenever I get going on the project later in

Not the full 30 amps is being consumed. That's the circuit breaker rating
which is around twice the normal current draw -fine for this application.
Surge current is handled well by the breaker upon startup. The rack Power
Controllers bring up the CPU, DASD's and tape in a sequential manner.
