If they failed / didn't start, then they would be looked at by a technician in the production area.
Ah right. I was thinking of just making a couple of riser boards so I could at least have the RAM board a few inches above the main board to be able to get probes etc in. Easy done with a couple of protoboards and some SIP headers etc.

The D1122 Micron Computer Program Data Recorder from Altronics proved to be quite reliable although their automatic rewind button release didn't always work.
Modern audio WAV players work reliably.
Indeed, I forgot to report back. My usual 'laptop with mono cable running Audacity' worked every time with the increased voltage so I'm a happy bunny. Just need to sort the sound now. As it happens, I do have several proper data recorder types, one with phase inversion, so if the laptop hadn't have worked I could have resorted to making cassettes again like the old days
