The easiest way is to keep the old osc board design. IMHO the necessary
additions  are: PWM instead of fixed squares, a dedicated LFO, VCO sync,
an overall octave switch (takes all 3 VCOs up or down), four stages
envelope (ADSR),  rotary switch to address vco or noise signal to the ext
in, different resistance value for the cut off and emphasis pots for a more
linear response (not like real mins where nothing happens from 0 to 8 and
it is all between 8 and 10), and (why not?) an envelope for VCO's pitch (so
I can play Hoedown on it).
