Also does this machine use an isolating transformer? I would like to see if it’s maybe a power supply or noise issue but there are no markings on the transformer.

I've scoped the voltages on the main board and they are all clean and rock solid. I've also upgraded the eproms on the board to version 51.08 and it still does the same thing. The errors on the screen change when something else changes. For example I insert a coin and the text for the winning hands change. So now that I know my program is good I'm leaning towards a stuck bit somewhere. Does anybody have a schematic or manual someplace?

I just fixed one of those problems. Your signals may look good but if you replace the 7 sockets on the board the confetti will go away.
