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
