yes, this is a great group/list. i cant imagine trying to maintain a cs80 without it, as we all dont have the option of a local synth tech!
one question for you guys: i've got some new IG chips coming in to replace what i believe are dead chips. my plan is:
1-take out a properly working M-board
2- measure voltage on all pins of VCO, VCF, and EG chips so i know what SHOULD be coming in/going out.
3-check voltage on the sockets of the non-working m-boards before putting in new IG chips.
am i missing anything here? any advice?
thanks a bunch, guys.

Thank you Kyle! Now that you say it, I think I have done it on the CS-50,
too. But that has been ages ago, and the CS50 only cost me the equivalent of
300 Dollars. :) So I thought I better be sure before taking any risk on the
'80!

Thanks for your nice words. Yes, I love to modiy and also to share the mods.
But for the near future, it will be all the other way round: taking all the
advice I can get from the experts on this list to fix all the little bugs.
I'm glad the synth is in such a great shape overall, and especially on the M
boards, and holds its tuning.
With a little help of my friends here, I'll certainly fix the other things.
What a great list this is!
JH.
