One of the inputs (movement up) didn't work on my friend's Robotron. We swapped I/O boards with his Stargate to see if that was the problem, and it is the problem. I checked the resistors that are the first thing that you hit when you hit the I/O board and they seem fine. I'm not sure how to test capacitors with the equipment that I have (fairly new at electronics). What would you do next to debug the problem?
Thanks!
