Looks like yours were built and wired from the earlier revision to the drop targets and schematics, and Alien Poker proved to be tricky to get the wiring right without having a machine physically here to look at. The target set in your machine is from the first batch I did for Alien Poker, which ended up not quite working right as you noticed. It's wired to use the momentary contacts in the middle of the board, not the constant contacts at the bottom. If you change the wiring you'll also need to move the diodes on the PCB's too, and make sure the stripe on the diode matches the orientation shown in the diagram.

I know not everybody is comfortable doing surface mount work, so I can also send you a fresh set if you feel it's outside your comfort zone.

Yep, and same thing that threw me off when I did the original schematics. I got so used to everything being momentary.
