I finally finished the calibration and now have a very nice Memorymoog to play!
Getting the voices in tune. Took a long time but I followed the manual backwards, so I actually did the full voice calibration by tuning each oscillator on each voice to the correct frequency.
Once I got to the software tuning section, I knew I'd hit the dreaded upside-down characters and needed a solution that wasn't going to break my stones. I didn't have a mirror. But, I came up with a pretty novel idea... I got out my DV video camera and ran it live pointing at the values. I hooked it up to a spare flat-panel TV and flipped the TV upside down
The software tuning went pretty quick, and I only had to adjust the range trimpot. I was thinking that it was possible, having done all the extended voice tuning ahead of time, that I may have expedited the software tuning since the values were maybe now closer? i don't know, but I got every voice in range fairly quickly. I think I only had one that was 7F all across, but every one of them had a 7F value in there and the other 2 values were right in line.
I now have a very nice, very playable AND very stable (it seems so far) early #SN Memorymoog. I must have played it until 2 in the morning. I feel very accomplished for having taken this on, and I think I'm at the point of leaving it alone unless something funky crops up. This isn't an instrument I want to tear down a lot.
