Re: One very bright unresponsive row on Peggy 2

Regarding your suggestion about Q1, I double checked and I can find no evidence of a short between the emitter and collector pins of Q1.  I replaced the transistor once before trying to debug, but I will try it again in case somehow it turns out to be the culprit.    Edit:  I am an idiot.  I located the short between the collector and emitter of Q1, as you said I would.  The story of how I am only finding it now is too embarassing to publicly relate :)  Anyway, problem solved!  You are the man.
