Thanks JRL.

I took your advice and did the alcohol wash and pram battery replacement.

I was able, with the help of a friend, to locate a cap with the value I needed. I didn't swap out all the caps, just the bad one. The results are the SE FDHD is booting, happy and running system 6.0.8 again and the sequencences my nephew did in PERFORMER 2.2 are available again. I did make a backup of all essential data. :b&w:
