HP 9100A/B How many transistors and diodes?

[brouhaha]

The inductively coupled PCB ROM memory in the bottom of the machine contains 512 diodes, one per memory word. While that memory stores 32,768 bits, there are no electronic components (or even ferrite cores) replicated on a per-bit basis. It is an amazing technology developed specifically for the 9100, and then immediately obsoleted.
