Has anyone wired up the coin return as a button?
I was considering wiring the left and right coin returns as buttons and then using them as the "credit 1" and "credit 2" buttons for my mame cabinet...
...nevermind...found a couple links! That said...if you have a good way of accomplishing this, please speak up.

I was thinking about doing the same... Can you post the links you found on the topic?
Thanks!
-
yes please post. I have seen posts on it but nothing saying how to do it.

Yup.....
The method I used without adding an extra microswitch is a mechanical one.... This is what I did with mine, which actually has no mech at all.

The brass wire running from the red reject lever down to the bottom microswitch, acivates the switch, when you press the reject, just as though a coin had passed it. So you can either put a coin in which gives you 1 Credit or push the reject button which also gives you 1 credit. I don't usually tell my friends about the reject button till they've stuck a few coins in there, >:D >:D >:D....
You might have to route the wire differently to avoid your coin mech, if you have one installed.
Sorry the picture is a bit rough. it's the only one I have from before it was installed.

Are you talking about that brass wire in the middle of the coin door? If so any idea where you got it? That seems to easy, no wiring or anything. How is it connected to the reject button?

See the yellow reject button (top left) next to that is the red lever which normally presses on the reject mechanism of a coin mech.... the brass wire runs from there down through a small hole in the base of the coin mech support.... It then has a 90 degree bend in it and that piece sits on top of the coin wire of the microswitch. So when you press the reject the brass wire is pushed downwards by the red lever, and pushes on the coin switch.
The brass wire is just pushed through a small hole in the red lever and bent over at the end to keep it there.
Where did I get the brass wire?? It's cut from a wire coat hanger... The steel sort would work just as well.
Took 15 mins to make, including drilling the holes and bending the wire. There are actually two on that door because it's a dual coin slot door. The one on the oposite side has the coin switch wired to coin1 input on the Keywiz and the one you can see in the picture goes to coin2 input.
Directly behind the brass wire you can see the cardboard tube that carries coins fron the top of the mech cradle down to the coin switch, which is the job a mech would normally do.
The only down side to not having a mech installed, is that whatever coin you put in there, you only get 1 credit and it doesn't reject any coins. But at home that really doesn't matter much.

I did add coin switches, wired in parallel with the regular switches:

These go through a toggle switch inside the coin door so I can turn off the coin reject switches:

The other two buttons on this panel are also wired as coin buttons so I can add credits with the door open when I'm doing testing.

I have the whole coin mech so I don't think the wire trick will work for me, no room. I have no clue how to wire the switches up to make it work. Maybe if I sit down and look at it I could figure it out but right now I can't.

It should still work fine.... All you have to do is to route the wire outside of the coin mech. A few bends in the wire to move it beyond the coin mech should do the trick... all you need is a small wire loop near the bottom to keep it in position and you could attach that wire loop to the mech frame with a small screw.
