Can anyone verify for me if the pins between the interconnect cables are reversed between the main board and the auxiliary board -- meaning, the wire at pin #1 on the main board is supposed to be in pin #24 location on the auxiliary board?

The original cable and my new Bob Roberts replacement look identical, connector-wise, and the original Atari schematic seems to correlate they should be reversed (no detail of individual wires, just flipped numbers - see pic), but I just wanted to check here with someone before possibly screwing this up and maybe having an expensive repair as a result.

My concern would be that perhaps the Bob Roberts one was created with the edge connector reversed, and I should fix that before proceeding. His is colored wires, and my original is all-white, so it highlights this issue.

Help a paranoid guy out... thanks!

Answered my own question by saying "screw it" after nobody responded... the cables do reverse and what is in pin #1 location on the main board should be in pin #24 location on the auxiliary board. Game is working fine.

Seems strange to not have the colors correspond between the two, but it is what it is.

Hope this helps somebody else out at some point in the future...
 
If you look at the picture of the schematic you posted you will see that it does in fact show pin 1 going to pin 24.

Glad you go it working.

Yes, I know, I was over-thinking it.

I'm so used to wires color-mapping to the same pin between boards that my brain couldn't handle that a yellow wire would be a gray wire on pin #1 between the two boards. :D
 
LOL.. I've worked on stuff that is completely wired with black wire before. In those cases it's always the black wire.

I hate when I over complicate things.
