Coin Door Power off reject solenoid.
sWampy:
Anyone know what voltage the little solenoids on coin doors run at? I was thinking it would be totally cool to hook them up to a relay hooked to the lpt port of the computer, where the front end could shut them on/off. So if you had mame loaded and inserted a quarter, it would accept it, but if you were just in the frontend, it would just drop through. Sortof silly I know, but I'm bored. I couldn't seem to find where to order new ones, and I don't want to burn up the only 2 that I have that came with my old defender cabinet.
So does anyone know what voltage the solenoids in the coin door of a defender took to allow acceptance of coins?
Thenasty:
its usually 24vdc. I think I have seen 12vdc and I know about 10vdc cause I have one (but it different than what you have).
Chances are, yours is 24vdc but you can apply the 12vdc to it to see if its get enough juice to pull that TAB.
Just in case you don't know how the Lockout Coil works.
It only accepts coins when power is applied to it and rejects coins when the power is cut or off.
But your idea is not the first but I have not seen anyone finish it cause it need modifying in the MAME source or the Frontend.
Maybe running a BAT file that triggers the POWER on/off to the coil is the quickie mod. Let us know what you come up with.
Ken Layton:
Coin Lockout Coils come in these different voltages:
6 VDC
10 VDC (special order for Atari)
12 VDC
24 VDC
24 VAC
48 VDC
120 VAC
Since you have a Defender cabinet then it's likely you have 24VDC coils.
Lockout coils do not interchange between coin door manufacturers. If you had a Coinco coin door (for example) you would need to have Coinco lockout coils.
Rocky:
My Moon Patrol lockout coils are 24v.

With AdvanceMame you have control over the Keyboard led's with scripts. No need to change code or compile. You could turn on say the scroll lock led when a game is running which could activate the solenoid via a relay.
