Hi again, dhenry! Thank you for your reply!
I would start by checking if the mcu gets power; if it is out of reset; if the oscillator is working, etc. and back to the regulators, etc.
The processor is getting power... Rechargable 9-volt battery at 8.88v. Power at pins 20 & 21 fluctuates between 4.95-4.97 volts.
How can I tell if the oscillator is working ?? I have been suspect of this. With a pair of tweezers... just barely touching the oscillator... the top moves quite freely... It doesn't appear stable. How can I test the oscillator?? I don't have a scope.
