I remember that from when I was doing the multigame code-- my test setup
was a bunch of bare boards on the workbench, and I was tagging inputs
with a jumper-wire. Hard to get credits sometimes. ;-)

Wasn't the coin circuitry tied to INT on the Z-80? That should be
really easy code to find.

Hmmmm. Probably not *too* tough. I should have done it when I was
still doing the Sega Multigame, but after patching everything for the
control panels I was a little sick of it. ;-)

I'll look at my listings and see if it looks easy to patch or not. Sega
took great delight in making all sorts of screwy jumps and crap through
(HL) to make my life hell. (Yes, I'm sure they did it specifically to
annoy *me*... ;-)
