Me too.  Got a garage sale Poly-800 sitting useless in the basement
right now.  It works fine, but is just so dang boring.  Cutoff
frequency, resonance - oh, and routing the oscillator output to
frequency cutoff, to have filter FM for extra klangy keyboard
intervals.  (Super fun!)  If anyone has any schematics and can suggest
some good solder points, I'm willing to Frankenstein my 800.
