Here's my board. One photo of discrete component complete. One photo of board complete. One photo of the board working on the bench. Success on first power up. Amazing! It passed all the bench tests available (verified the data and address bus of the ribbon cable connectors).

I can concur with Pin_Guy that the bulk of the work is bending the discrete components. I did them ALL by hand (in front of the TV). A friend of mine told me about the lead forming tool so I ordered one for my next board.

This board is strictly for the bench as my known good board.

Thanks. You clearly have a good eye for detail. It was an experiment (first try) but I did it because I wanted to keep this a bench board and for me those two ICs are the most frequently swapped.

I am re-using an arcade switching power supply from a re-import that was being used to prop up the +5VDC line. I fixed the rectifier and capacitor and re-purposed the power supply.

I got this from the Theatre of Magic manual. Seems like this is the information that you are looking for.
