Well, I was going to ask about this on here at some point, but is there
anyone on the list familiar with guts of Yamaha's DX7 II-FD? A number
of years ago, one of my co-workers dumped her dead DX7 on me.

It's been dragged across the country once and stored up in my attic for
a while, until the last week or so. The initial symptoms were that none
of its buttons worked and it failed to generate any sound. Inside I
found a small and very dead battery soldered to the board which holds
the main processors and memory. After soldering in a proper battery
holder and replacing the battery, the synth lit up very happily once I
powered it on. All the front buttons seem to work, and I can choose
between the numerous available patches, but still there's no sound. At
least I'm not able to get anything out of the headphone jack or the two
audio jacks on the back of the keyboard.

Does anyone happen to have any additional adice for me or schematics
for this fellow?
