Vintage Simmons Drums (UK) Users Group

Greetings all...
   I have recently acquired a Digital Clap Trap in desperate need of 
some tlc and was wondering if anyone out there had any documentation 
for this unit vis-à-vis manuals and/or schematics they could
provide me with... there's virtually nothing on the web that I could 
find. Anything would be greatly appreciated.

Thanx...
   Joe
