So I'm back working on the Altair. The RAM is good, I can read & write to it, but when it comes to executing anything, it's not doing a damn thing. When I reset, all the status lights look good (MEMR, MI, and WO are lit). When I single step, the STACK LED will light up for the next two steps, and then it will go back to the way it was before. It will repeat the same pattern as long as I keep hitting step. When I go from examining address 0 and then hitting step, it will go to a random address each time. In other words, it seems to be completely ignoring anything in RAM, but it has the same execution pattern every time.
I'm not sure if there's more than one problem going on here with the CPU board, but I'm a bit puzzled as to where the problem would be.
