I'm about to get the service manual for SH-1000. I opened it and the first thing I noticed was the presence of several "custom made" ICs. They are not exactly custom made in the sense the IC was designed for Roland. Roland just took a bunch of components, solded into a single small board and covered it with epoxi. I believe this was a security measure to avoid circuit copies but it makes the repair far more dificult.

Let me take the service manual and maybe I can help you with your SH-1000.

Cheers,
Arnaldo.
