They were referenced in the "This Old Pinball" repair tutorial.
Their website is dead so I dont know what became of them.

You could probably use the documentation for a Great Plains rectifier board, perhaps its close enough to work for you.

You could use the games schematic and that would tell you the function of the output pins.

That's the board made by Tom Callahan. He changed the name of his company from Repair Connection to Pin-Logic.

Here's his website:

Is he back in business? He was closed up and looking to sell the site the last time I checked.

Yup, he's back in business.

Tom is alive, well and in business.

You can email him for a copy of the manual for your power supply board.

can't decide what would be worse. Making that connector or hard soldering xfrmr wires to the pcb.

Theres several types of board that he sells. I bought two for early ballys (kiss) and soldered the transformer wires. It wasnt too bad, labeled everything and went to work. Didnt take long. I would think the connector would be better, but it seemed like the install would be harder. Board works great though

Over the years I've installed a couple of his boards. I did the soldered version and it was fine. A very reliable board in my opinion.

I wouldn't go the connector route between the transformer and rectifier board. Connections are the weak point of this board and doubling the number of connections is increasing future "fun".
Best bet for reliability is what Ken said, just solder the wires to the board.

20 amp rating on GI fuse. I wonder how many redundant connections the GI has in that connector block. THose contacts are probably not rated for 20amp.
