Okay, I've gotten the code done, but now
I am seeing something very interesting.

I'm running my code against a scope, and
everything looks beautiful... Then..

If I power the circuit & the servo from
the same +5V power supply, things work
okay for a minute but then the 16F84
"locks" (sorry for the technical term,
but I'm really not sure what happens,
it just quits running my code).

If I power the servo seperately from
the circuit, the servo continuously
rotates (still watching the scope, the
signal is perfect).

If I power the servo seperately, but
connect the grounds of the two power
supplies together, things work okay
for a minute and then the 16F84 "locks".

I've tried the servo signal wire directly
into PORTB/0, through a resistor to PORTB/0,
through a diode to PORTB/0, through a
resistor and a diode to PORTB/0, all with
the same results...

Does anybody have any ideas??  This one is
really stumping me.

I've checked power power supplies, voltages
are correct (+4.9V) and the signal looks
clean.  I have tied MCLR & VDD to +5V, and
VSS to GND.
