I'm intending on purchasing a coin mechanism with a single micro switch on it. It will be used with an ipac2, I understand that when a token or coin is passed through the mech the micro switch registers a coin in (5).
Are there any limitations to doing it this way? Can the coin in (5) input function be used as a credit to player 2 in 99% of games? I recall there being a separate slot in a number of the larger two and four player games hence having 6,7 and 8 also acting like a coin in, is there a way around the problem in such situations?

you can config mame so each coin deposit triggers a credit for player one, two, three, and four.
-
If you are only buying a single mech door for budget reasons I have 4 double mech doors leftover from some waterlogged arcade dartboards I parted out a while back. I'll sell them cheaper than a new single mech door.
Some games really NEED to be credited separately for each player. Sure you can configure mame so it credits each player with each coin but most games aren't really going to like that. Plenty of them will eventually autostart the other players even if they aren't there.

Thanks are the 2 player mechs you have easy enough to wire up? Are they of a specific denomination? I'm UK based and will need it ideally by next Wednesday?

Nevermind, I can't economically ship you a coin door from America and have it there next wed.

if you are just looking at 2 players, you can hook up a "shift" button.
the common would be from your coin drop line from the door and out from your NC (p1) and NO (p2) leads would be your player 1 and player 2 coinup, going to your ipac.
that way you just drop a coin to credit player 1 and hold the button and drop a coin to credit player 2.

This would be the best way I could think of to do it (other than using the default shifted IPAC keys of P1 start + P1 button 1 = coin 1, and P1 start + P2 button 1 = Coin 2)

i'd just use add 2 micro-momentary switches to the face of the coin door. Its probably only a 1/8 inch hole and inconspicuous enough.
I've found that the novelty of the coin mech wares off fairly quickly.

Not for me. None of my machines have a free credit button. The kids especially get a kick out of it. Tokens all the way!

There's also the old "put a microswitch behind the return mechanism" trick, so when you press the coin return you get a credit. ;D

I'm liking the idea of this, but from a wiring point of view I'm having trouble getting my head around it. I'm happy to do whatever providing I can trigger a coin in for player 1 and 2 independently.
If I got players to hold the P1 start (1) and set the ipac to issue a player 1 coin if the player one coin (5) button was triggered in combination with the P1 button being held - so 1 & 5 = 5, then do the same for player 2 start so 2 & 5 = 6? Would that work and is it even possible?
Would I not get an issue whereby a p1 game would start right away because the key press triggered by the coin will only be momentary? So the ipac would get 1&5=5(p1 coin) then player one start (1) right away?
Sorry for all the dumb questions, I have a limited amount of time to put this together so it's a challenge at the moment!!!
Edit - can you not change how games such as the Simpsons accept coins with the mame system menu?
Edit2 - I've done some testing and by the looks of it I'll be fine with just a single coin mech, if you run the 2 player rom of the Simpsons and TMNT credit in on slot 1 gives player 2 the ability to start a game and select a character.
