I talked to Bojan (author of that MIDI retrofit) a few times via email.
He certainly knows his stuff. His disassembled and annotated pages of the
KLM-366 and KLM-367 microcontrollers are immaculate, and have been very
helpful in my work trying to my the MIDI version of my replacement KLM-367
board.
On that note, I just received the bare boards for the production run of
KLM-367 clone circuit boards. I now have all the parts needed to have my
assembly house do the production run. These are the direct drop-in boards
that entirely replace battery-damaged/ruined KLM-367 patch manager boards
and use the original 8048 microcontroller (not PICs).
When I have units ready to sell, I'll let this list know. Those who
sent emails asking will also receive private emails once they are ready to
ship. At least I can say that time is getting close at last.
Information on this project, for those who do not know about it already,
is here:
http://www.oldcrows.net/~oldcrow/synth/korg/polysix/crowlm367/ One note: these are not the 'new' KLM-367 version I am currently working
on, which will use PIC microcontrollers and feature keyboard and parameter
MIDI as well as flash-based patch storage (no battery anymore!) This
version is many months away yet as the coding for them is quite complex.
