Re: K5M - need IC26 EPROM file

I made it start!!

Something seems broken on the K5m's reset circuit, I lifted IC15 (the reset
controller) and now the synth starts one out of three times, so it needs
fixing there. Once it starts everything seems to work ok so I'm on the
right track.

Thank you very much for all your help.
