We'd love to, if we could find them...

People usual don't post schematics "out of deference to EMS..." but  
their website hasn't been updated in _10 years_, which makes it hard  
for me to take them seriously as viable synth-manufacturing entity.

(Of course, STS doesn't even have a website, which makes me take them  
even less seriously).
