I have a new DMM and a Logic Probe, built a second prototype scope on breadboard (let's just say it's not ready and I don't have a scope:) )
I did socket the battery with a good coin-type holder, so looks like an Ohmmeter check with the DMM with Polysix OFF is doable.
Very cool, thanks man.

If you have a scope, check every signal that connects to the RAM chip.
If you only have a meter, you can check resistance from the RAM signals
to other chips that they hook to. If your battery is socketed, remove it,
and do the ohmmeter checks with the synth powered down of course.
Measuring resistance with a DMM on signals that have voltage on
them doesn't work.
