S+ Coin Comparitor boards

I was "puttering" around...lol
Look at the serious modifications done to this top board!!! wow!
Whoever did this completely modified it to totally bypass several components...sweet!
They know their board level repairs! 
But what was done really?
There's no heat damage to the top one while the bottom one looks cooked around the red LED.
[Input Testing] will be performed shortly and I'll post my results!
Anybody have any suggestions on how to make an external coin mech tester?
I could stick them in "Young Frankenstein" but I wanted something for my bench.

Hi

If I remember right most of the parts on the connector side of the board are opwer related. The CC16 was designed for a large range of input voltages and all those parts are mostly there to drop the voltages. When I started in Gaming one of our projects was to do an entire circuit analysis of the CC16 board. I will see if I still have it somewhere. All you need for a tester is a voltage source and if you use a lockout option some input signal . There is an Coin Mech test rig available from them or happ but its expensive.

As always simple is better - In one of the casino's i worked before we had the fancy programmable coin acceptors in the high denom are (Condor I think). Anyway someone figured out a way to clone the tokens and the acceptors did not pick them up. I ended up building a contraption using a hopper that fed into a CC16 to sort the fakes and the real coins until we could get software updates for the programmable comparator.

I want to make mine own Test stand for these and
play with them using probes, multimeters and such...
