I remember when doing standby power generator tests we had to remember to off-line all the

Hi all,
Back in the early 70's I was an operator on an IBM 360/40 with 4
tapedrives. Nobody could understand that sometimes a tape transfer
would stop saying "end of tape", mainly around 3 PM,
It was also
well-known that you should not allow flash pictures to be taken in
the machine room, as ALL the tape drives would unload simultaneously when
the flash went off.
