I just repinned a Buck Rogers and have a small issue after putting it back together.

The issue is that ones don’t display on players 3 and 4 displays.

Here’s what I know.

1. The ones displayed correctly before repinning.
2. When in display test mode the ones do not display for players 3 and 4.
3. The game is running a very early version ni-wumpf cpu with early version ROM.

I hope I didn’t get a pin off. I was bery meticulous about putting pins back in the correct positions. Bit not good enough to take a before picture.

Which is why I am here. Can someone post a photo of A1J2 display connector showing the wire colors and positions? I’ve attached a picture below of these connectors for this game afrer repinning. Thanks for the help.

The ones on displays 3&4 are the 'h' Segment on Segment Group B, which is connected to A1-J2-Pin19.
Your Pin19 is empty, so there must be 'somewhere' in your pin a cable which is not connected.
According to the manual it is a 'white-yellow-black' cable.

I only had a Joker Poker manual to go by and it indicated pins 18 and 19 drove the “h” segments which make up the one and could not make sense of the connector on this game as there are no stray wires on the bundle but I’ll look again seeing TheWiz’s photo. Thank you to both of you.

We found the missing wire on dead pins on the adjacent connector A1J3. I got it mixed up when I first started repinning.

Thanks for the help.
