Some year ago I posted a schematic of a thing with a 6850 and a couple of
hex inverters that sent program change status and data. It went to the
music machine archives at hyperreal but I don't know if it's still there or
not. The problems is, I haven't seen a 6850 or seen one for sale in a long

I beg your pardon :-? C'mon Magnus, you can really imagine all the things
that can go wrong at the outset of a project? I agree with you about
patching, of course. It's hard to pull out big chunks of code and throw
them away, but "old-timers" know that the working code that replaces it
will probably be a lot tighter. 

It's about learning and the errors are the teachers.
