Macintosh LC 630 DOS: MIDI modification

When I originally purchased my LC 630 DOS I had assumed that I could connect a MIDI adapter to the Joystick port like I could for my old PC, but after some reading I found out that wasn’t the case. Luckily someone discovered that you can get MIDI out by directly connecting to pin 30 of the Vibra 16 chip on the DOS compatibility card’s sound card on their Macintosh PPC 6100/66 system, and I believe that the same type of modification can be done for the LC 630 (to be determined, will update after it is done).
