I don't think there is anything wrong with M/N, but the A1 in
HP5065 suffers from dead/drifting/dying and obsolete components
in the divider.

I tried replacing the divider with a microcontroller, and that
seemed to work, but as I mentioned, my end-plans are slightly
more ambitious.

Never attribute to malice what can adequately be explained by incompetence.
