Post by: junkman on January 03, 2011, 08:25:00 PM im wondering what the I/O board does . what does it control . i have a machine that im working on and it is a max bet of 3 coins bet and it will only take two and sends the third to the payout tray . im trying to figure out if it is the wrong mpu board for the machine. or is the wrong I/O board. i have more I/O boards but im not sur what they do for the machine.or if its the mpu board can i change out the chips to make it right. or the glass to match the board . im sure someone has run into this before . can someone help me see the light . thank you all so much for your help this is a fun project. :99-

So you would have to change the glass or for most games the easy way is to just change the chip. Title: Re: I/O board help! Post by: junkman on January 03, 2011, 09:03:13 PM The game is five grand.made in
