My experience has been that +5 failing doesn't kill much (if anything) off. Now losing the -5v is the kiss of death for your 4116s.. :)
Pwhew. I was bracing for the worst.
If you're not a "purist" (going for the complete restoration -- Hi Chris!) I'd definitely recommend taking this opportunity to change out the crappy wms supply and going to a switcher.
I'm not a purist, mostly I just like to play working games. :) I'll throw in a switcher. But I will leave the original PS in it, just to keep all the parts there, and because it's a "numbers matching" game. Google says I should also replace the 3 AA batteries with a lithium, so I guess I'll do that too. The holder had corroded anyway.
If you did have some of the ram wiped out you might consider the 4164 hack (which also doesn't need the negative voltage).
If I lost some RAM, I'll probably just replace it. My games see about 4 hours a month of on time, and I'd probably cause more trouble than I'd fix. The switcher should keep the RAM happy, anyway. Sean
