PS: I wonder how many people here have -11/45's? ISTR one other, but they aren't
common.


I have one 11/45, and one 11/55.
Most of the CPU boards in the 11/55 are the same as the ones in the 11/45,
but I have the M8120 and 4 M8121 boards (32kW bipolar RAM). It is a bit
weird, but in the 11/55 are also two G114 boards (4kW MOS RAM), IIRC.

Both will need a thorough inspection before powering up!
