My little project lately has been trying to work with the MIDI port on model 1 Wondermegas. And I had some success tonight!
This is really awesome, IMO! As someone who loves 1990s MIDI gear and who's been doing a bit MegaDrive programming in the past, I find this really exciting. Thanks a lot for researching this nearly lost piece of the MegaDrive history. (I'm really tempted to get back into MD programming now.)
