Reply to "Lionel CW-80 - problem"

The LM324 is a simple op-amp, it doesn't get programmed.a  However!  I posted the wrong diagram!

The programmable part in this picture is the MC68HC908, if that part is bad, you're out of luck.  However, the failures are far more likely to be at the top of the diagram, specifically the BTA24-600CWRG is a likely failure candidate.
