Saturn Communications Port Pin-Out

[enyalij]

Looking for the schematics of the Saturns communications port, specifically how it send/receives MIDI signals and any Power outputs and Grounds.
I know the lower half of pins are linked to the MIDI but i'm not sure exactly what signal is going to each pin.

iv provided a quote of someone mentioning what i am describing.

I don't have a list for which games use the keyboard. However, it is a completely normal MIDI keyboard, and any keyboard with a MIDI input/output can be used for those games. However you do need the midi plug which goes into the communication port. It's a straight passthrough cable without any active components though, so if you can't find the cable you could probably solder a midi input into the console. I recall seeing the schematics somewhere.

Thanks For Any Information!

There was one Japanese game, I think Saturn Music School (not sure) that had MIDI compatibility and came with a dongle/adapter. It was a straight passthrough from the communications port to two midi plugs with no onboard components.

The port pinout is there in the service manuals.

edit: yeah, it's Saturn Music School.
