Hooked up the coin counter on the pacman this past weekend and it is working fine. Is there any way to reset that counter or would I have to buy a new one?
Thanx,
Bitnerd

The only way you get that back to 00000000 is open it up and adjust it or keep cyling it until you reach it. I had open mine up and manage to do it and done it carefully. Good luck

Some of the metal-enclosed meters have a couple of 'tabs' on the bottom that when carefully squeezed will allow you to slide off the top cover to access the meter guts. Some meters might be able to be carefully reset, but these were designed NOT to be resetable. Besides a replacement meter is only $5.

Thanx guys, I may just pop one open for "chits and grins" to see wassup but y'all make a good point, if I can just get a new one for 5 bucks then what the hay. I guess I would get a new one from Happ?
Thanx,
Bitnerd.

Happ, Bob Roberts, or just about any of a dozen amusement/vending supply companies have 'em.

When I put together my Time Pilot I took a coin counter apart and reset it to zero for the machine.

Now a BETTER coin counter question would be.
"How the heck can you get these things to work with Mame?"

That is a good question and one I was going to ask when I finish this pac man and start maming out a ms pacman cab I have.

Put it in series with the coin counter on then ground side. It takes 5 v. Just hook it up so that it's made when the coin switch is made.

I've done it. I even had it connected to a keyboard hack (I made a circuit, using an optoisolator). This is a while back but with an IPAC encoder, just make sure you use a coin counter that is 5v or a 6v and the rest is easy.

I have the general idea, but I don't seem to understand how to wire it without shooting 5 volts down the input line for the coin switch.

Randy Fromm has various coin meter hookups on his super secret tech page.

here is a radft draft...

As soon as I can afford it, I am going to get some tapes from Mr. Fromm.

TheNasty: Thanks a ton for pointing me here. I had done some searching and even started a thread on this subject, but never got this far.
I wired up my coin counter, as per the sketch, and it works fantastically!
However, I'd like to try one modification. I have two coin switches in my coin door (and actually 4 credit buttons on my panel 2 of which are wired to the coin door).
Anyways, I want to increment the counter on all 4 inputs. Right now if I wire up the Meter to all 4 grounds then when I hit player 4's coin switch all of coin switches fire! These 4 coin inputs *have* to be separate for games like The Simpsons - where there was no start button, you put a coin into the slot of which character you wanted to play.
I'm looking at the sketch and I think what I need is some sort of one way electrical component between the meter and each coin switch. That way when I press the player 1 coin button, players 2, 3 & 4 do not fire, but the meter still increments.
I've attached an updated drawing. Is there such a "Gizmo"?
Is there another way to do this that I'm not realizing? (Ipac reprogramming?)

Maybe Im wrong, but I believe the "gizmo" is known as a DIODE :) It prevents electricity from going 2 ways, so you can basically have each path as it's own. I THINK this should work (see pic). What happens is, lets say no buttons are pressed. Current is flowing from the +5 on the ipac switch, to the ground, but is stopped by the microswitch. Therefore, incomplete circuit. The meter won't work either because it will only allow current into it if the current is negative, which it isnt. Nothing happens. Now, button 1 gets pressed. The ground current flows and the + current flows, completing the circuit. Now a button press is determined. With the GND flowing, the diodes allow the current because it is negative, spinning the meter.

Visit my BYO Gadget on my www page. I put it there how to connect 4 switches w/tyhe ipac and 1 counter.

I have a bunch of practically new coin counters if anyone wants to buy them for a good price. :) Most of them have 2 or 3 counts on them (probably done at the factory when testing because they have obviously never been used).

Do I need a 5V Diode?

Joseph Elwell.
According to thenasty's schematic, you will need 1 diode for each player coin control switch being counted (1 for player 1, 1 for player 2..etc.).
The diode appears to go between the iPac and the NO connector on the player x microswitch.
With COM(s) from the coin-in switch, going to the hot side of the counter.
Finallly GND from the counter going to GND on the iPac
I haven't tried that yet, but I have test wired the same solution for a brief second without the diodes, and it only increments when the 5VDC power is first applied, and not with each button push, or in my case each time the coin drop wire microswitch is kicked...
