Hello Jcee,

J>>But, if the chip was blown the program that is on it wouldn't work? Or am I wrong? I can run the program that is on the chip that I can't erase.<<

Not necessarily...the part that programs the chip may be blown...*if* that is the only chip it does it on. if your other chips work, then there is something else wrong. Voltages, ICSP pins not disconnected from circuit, or something...

I once blew a PWM on a 648A.... everything on the chip worked, except the PWM. <g>. So I converted that chip into a Serial LCD chip... <g>.
