bill acceptors are coded for a cashcode type serial interface for the MDB protocol. you would need some kind of signal convertor to decode the datastream to find out what bill was inserted.
you will also need to send a signal to enable the acceptor to be able to accept bills... otherwise you need to switch it over to stand alone mode.
Sorry for the thread necromancy (since it's only been like a year... ), but I wanted to share a quick update. I finally uploaded a 'showcase' video - check the first post!
This is really incredible. I just watched the entire video and was mesmerized. I have really never looked into any games other than MAME for my arcade cabinets because Zelda and Final Fantasy don't really appeal to me while standing up but it looks like you have hundreds of games that would be a lot of fun to play. And I'm not even talking about the pinball stuff! Now I need to do a deep dive to see what's out there... is there a list somewhere?
You should be really proud of this build - I bet when friends are over it's on the whole time.
Well tested both resistors (R0 & R39) and the capacitor (C15) by taking them out of circuit and they test fine. TRIAC was testing at odd ohms and continuity so I replaced it. Put everything back and got three games in before the ball release arm gave a small attempt at releasing balls when starting a game. the fuse was blow again.
Really getting disheartened on troubleshooting this one!
Looks good, and the good thing is, if you get rid of the io board you can actually install a cheap led controller board and it will take care of all the RGB leds, it does need a separate led control for the front white bezel, but they all look good. Now I have to play with the bill acceptor to see if I can get them to work. Im still not familiar with Mdb bill acceptors. Im not using amplifier to loose some weight, instead ill use Bluetooth for audio.
