Pinball life has them for $9.95. US .25 coin mech. Easy to change out inside the coin door. No need to buy a new coin door.

Yes. ( earlier I made the mistake of thinking it was one of the huge ones )

No.

You should put a picture up of what you have so it is better understood.

The coin mech should swap out easily. I added a pic of what a coin mech looks like.

I hope I'm understanding your question right. Coin mech.'s themselves are strictly mechanical. When they are installed, the coin goes through the coin door, through the coin mech. and then registers by tripping a micro switch that is attached to the coin door, underneath the coin mech. I will try to find a pic for you. Shouldn't be a ribbon cable there.

1. Yes - mounting is standard for coin mechs. May need to adjust the tits on the mech (in Alex's pics, the 'tits' or nubs) are seen protruding from the sides) but they'll fit.
2. No - the ribbon cable is an NRI interface, used for electronic multi-coin mechanisms. (And some single-coin mechanisms.) Your coin door MAY have a mechanical switch under where the Cashflow sits. This would need to be connected to wires - usually already ON the door - to trigger the coin input. If you're missing a switch, then you'll need to pick one up. (Available in many places..)

Any of these will work. You'll need the coin switch and wiring to the coin door interface board.

The MEI 330 is a programmable coin comparitor more common in Euro or Taiwan/Chinese made arcade games and the late model Megatouches. You can program a dozen different coins or token sizes. They are hit or miss with dependability id rather use a regular imonex mech.

Your door is missing the coin switch. However, you can easily get one (on phone, so I cannot find link for one at the moment), and it looks like the wiring is there - if you want to drop in a mechanical one.

The Cashflow 330's cannot be reprogrammed by the end user, you have to take it into an MEI distributor to get reprogrammed, and depending on the dist is costs anywhere between $75 to $150 to get done. (You can get a NEW NRI G.13 programmed to your specs from Suzo-Happ for about $120 - that's what I have in my TZ.)

So, you could go for a mechanical coin mech and accept one coin, get a coin switch and mount it in, likely cost you no more than $50 max, or go for a new electronic mech, accept multiple coins, plug-an-play.

Yes, the Mars Cashflow unit can be shipped to a Mars (MEI Global) service center to be reprogrammed for the coinage you want to use.

Get an old school mechanical one like I showed in pic.

if you actually intend to use it get an electronic mech, mechanical mechs have a lot of problems related to the angle of the door in pins in my experience operating them... plus you can get them from china for like $12 now
