Freeplay mod tech help

[Crash0]

Hey all
I am trying to install IGT FREEPLAY [size=78%]by Dupuhini[/size]
I built the board, programed the IC, but having some confusion as where and what to connect to.
I would prefer to do all hookups on MPU, if possible.
He has:

COIN optic A   Negative pulse   u12 pin 2
COIN optic B   Negative pulse   u12 pin 3
COIN optic C   Negative pulse   u12 pin 4
Are these the correct connections?


I have found VB+ and B Gnd, ok there


Last 1 need help with is where button wire goes, or do I need to physically route wire to button? (Button is cash out).
The schematics I have are hard to see, so it's making this more difficult to figure it out.
If anyone has done and installed this, help is appreciated. Thanks!

Think I may have found an alternative @ JP 50 on the comparator
Will give it a try

Hello Crash0


Cant find his (Dupuhinis) Freeplay device on the old site - I documented something similar her using a 8 pin PIC.

On mine I simply removed the wires from the change button and wired my device directly to it.
