Sorry for being the new guy and asking what are probably stupid questions. I have been given a Pinbot that has been setting in around for at least 10 years. I have read the manual for it that I found online, and have opened it up. I found that a bunch of the harnesses were unplugged from the main circuit board.
This is my first time ever looking inside a pinball machine but it doesn't look too bad.
So, my question is where to start? It powers up and gives a message of IRQ failure, then 26 ROM failure. After displaying that message it will start some sort of counting up at which point the flippers will work.
Thanks in advance.
