It's a bit of a shame to break up a running machine, to bodge the sound
chip into a crap 80s synth.

If you want to play around with a DOC chip, why not spend roughly twice
as much and buy an Ensoniq Mirage? You've got a DOC, a 6809 CPU that
will run any arbitrary code that you care to stick on a boot floppy, 16K
of OS RAM, 128K of sample RAM ∗and∗ eight proper Curtis filters to play
with. It's a well-documented platform with at least a partial
disassembly of the ROM and OS available.

Oh, and if you want to roll your own, it can run Forth:
