[sdiy] PS-3200 Clone - the VCF / VCA / ADSR PCBs

[jhaible]

Another little update from the PolyKorg project.

The biggest part of the design work is done: The layout of the "Gates"
boards. Where the original has the Korg-35 chips, I had to use discrete
components. I have put the PCB layout graphics online, at:
http://www.oldcrows.net/~jhaible/polykorg/jh_polykorg_clone.html

I have *not* built this yet (pcb manufacturer GS Elektronik is on
holidays), so the design is *untested*. (The circuit is tested,
because I've built one voice on protoboard, but the layout is not
verified.)
