Hi, my name is brian, I apologize now because I am new at this forum thing and slot machine ownership. I recently picked up an igt s plus barret top dollar machine for a Christmas present for my fiancée. It worked until the bonus game then I opened a can of worms. I found out that the mpu4 board in the top of the machine is bad. Battery leaked, ruined some resistors and probably the board. I have been on a hunt for a replacement with no luck. Could anyone help me or point me in the right place to find this crazy board that seems to no longer exist. Sorry I am not too good at this stuff
