[sdiy] Thomas Organ schematic links?

[DCMagnuson at aol.com]

Does anyone know where to get copies of Thomas Organ schematics?  I just got 
a mostly-dead organ from a friend, but it has a built in rythym generator 
that I'd like to modify.  I plan to add volume, tuning and decay controls to 
the stock percussion circuits as well as adding new trigger inputs to allow 
control from my analog sequencers.  

If anyone has a clue where to find / buy schematics for this, I'd appreciate 
any help you can offer.  It's a Thomas Organ "Playmate" 1100

The large wooden case has (2) 39-note keyboards as well as a 1-octave foot 
pedal.  I think this will be a great casing to put 3 monosynths in... and 
theres SO MUCH room inside for circuitry.... I'm excited.

Thanks in advance
