This is good progress, but I wonder why lifting IC6 kills the issue dead? I see that programmable input T0 is pin 1 and clock is 2 and 3. You don¹t suppose we have a track routing issue here? Perhaps there is noise from T0 being inducted into the clock pulse train from the adjacent track? Just got to finish a few issues and shall have a proper look at the problem. I now have my errant board in the lab. Cheers, Andy [Non-text portions of this message have been removed]
