When i first started with em pinballs it was with Bally Bingos. I found a playfield did it up and with the help of JOOP ( cannot remember his second name) I created a playable machine with over 50 different bally bingo games with. lcd tv displaying the different backglasses. So i decided to create a multi pinball machine, one cabinet into which i can install either flying carpet, duotron, bally bingo and maybe my chicago coin fiesta. The orginal solution was based on freetronic arduino shield with 6 mosfets, this worked great for flying carpet but not enough for duotron, so along comes cobrapin pinball controller, great. First converted the orginal gottlieb code to run on the stm32 using the arduino ide first set of test worked great. My solution uses on the stm32 as the game controller and the other board drives the pop bumpers, chimes, score reels etc. I have retained my seperate flipper controller but use a cobra pin aux board, just finish initial test will wire up and further test in the next day or so.

I have kept my orginal wiring as i really like jones plugs far far better than those JST / Molex types.
