    • Trackball Installation for SegaSonic with Original I/O Board

      Hello all,

      I have a SegaSonic PCB with the original I/O board and 3 Happ trackballs, but it's also my first arcade board and I'm pretty new to a lot of this stuff, so I'm hoping someone can help me figure out how to connect the two.

      My thought is I just need to wire the 6p connector of each Happ trackball to the I/O board's 26p AMP latch connector according to the PCB manual's pin-assignment chart, right? Which means I'd need wiring and the right connectors for both the trackball end and the I/O board end, right? Since a few people on here have done this before, does anyone know what part(s) I'd need specifically? I've seen online that at least for the AMP latch, I'll need a Molex C-Grid III connector (26p, 2.54mm). Can anyone confirm that?

      Really any help would be appreciated, thanks!
