Circuit Overview:
     Another monophonic analog single vco synth with 7 presets and good modulations etc. Sounds kind of like an ARP explorer in terms of what it can do.

Service Tips:
     Anyone? Steve Ridley informs me that this machine is more similar to the Roland SH in that the presets are hard wired rather than using some form of ROM chip like the ARP pro-soloist etc. LET ME KNOW IF I AM WRONG ABOUT THE KEYS IT TAKES! I can only see the front which appears to be the early fatar key like the SX-1000.

Lots of discrete parts I'm sure. Let me know if you need something.
