They are most likely referring to the Korg M1, not the Apple M1. Similar vintage as the DX7, so probably no electron microscope needed.

  Ah yes, that possibility exists as well. Good call.

  I wasn't planning on looking at either M1 :-)

    How about the D-50? ;-)

      I'm trying to avoid taking on more projects. The DX7 has a second custom chip, so if I look at that one too, I'll be busy for a while...
