  The part about transmitters sounds right, that number rings a bell.

  Are these mutually exclusive? My kids say I remember correctly, but
the wrong things.

|  What was ENIAC doing to need _that_much_ power in one stage of logic?

  How about driving busses with VERY high fanouts?

  Assuming that I'm right about the fanout... based on nothing but an
assumption that the builders DID have a reason, with the failure rates
they were getting, would one tube driving 1024 other circuits make more
sense than having more tubes and less fanout? They surely weren't trying
to avoid a gate delay at the speeds they ran.
