Re: Peter - Adding MIDI Port

Howdy,

Found it. Even found the original schematics:

Afaik, the only signals used are TxD and ground. Instead of converting the MFP TTL output to RS232, and then converting RS232 to MIDI, you could convert the TTL output from the MFP directly to MIDI.

Schematic:

I'm pretty drunk now, so you'll have to figure the rest out yourself.

good luck,

-- Peter
