9XD Gated waveform card

A card carrying gated waveform of variable amplitude, fed from the voltage regulator.

Attested by
Meyer's control drawings: "TO VOLTAGE REGULATOR UNIPOLAR VOLTAGE … PC9XD CARD / WAVEFORM VARIABLE AMPLITUDE GATED".

Worth knowing
The sources disagree. Meyer's schematic calls PC9XD the gated variable-amplitude waveform card; the replication notes in this archive title 9XD "The 7805/7812 Voltage Regulator Supply", which is the supply feeding it rather than the card itself. Recorded rather than resolved.
