Coin reject buttons as input in MAME!
Chris:
Exactly! The key lock was replaced with a dual-pole toggle switch, and the two buttons are in parallel with the coin switches, mapped to keys 5 and 6. One of these buttons is the original reset button from the AT case; the other is a Radio Shack momentary contact button to replace the Turbo on/off button.
So each coin entry has three switches in parallel: the actual coin switch and the credit button, which are always active, and the switches on the coin reject assemblies, which can be interrupted by the toggle switch. I use the toggle switch when I want to limit playing time: my daughter will pick a game, I'll open the coin door, turn off the free play, and use the credit buttons to add the number of credits I want her to have.

Instead of using the dual-throw toggle switch can this be done with the key lock? What I would like is to be able to have the key lock on the outside of the cabinet and just turn the key to shut off the free play. Also, how did you wire this so that one toggle switch shuts off both coin switches?

Taking your questions out of order...

You need a dual-pole switch A dual-pole switch (I accidentally said dual-throw originally in my last post, but I've corrected it) is essentially two switches in one case.

No, because it's not dual-pole... You'll need to find a dual-pole keyswitch, but I don't see any in the Mouser catalog...

Ok, thank you. PLAN B: hide the toggle switch inside the coin door like everyone else does.

It would be more like an arcade game that way, and that's one less key you need...
