Ah, history. I was privileged [;-}] to be able to pull the BIG RED HANDLE on the front of the IBM 7094's console, when smoke started coming out of the motor-generator set box! This box usually made a noise about like a jet plane, but exhaust was non-normal. For the record, the motor and the generator were each just big enough to straddle, like an electric horsie: about 75 amps at 220-3phase, I think. The generator bearing was welded to the shaft. After the generator shaft was turned back to roundness, it took a week to shake all the bugs out of the cpu. -- ---------- Dick Smith ..ihnp4!wlcrjs!rhesmith
