Closely related to this problem, I had trouble with unreliable start up
some time ago using the 16C61 chip (running at 20MHz), I built a number of
these circuits and they where all a bit iffy on start up. If I started to
probe around the reset pin the circuits would spring to life, I cured the
problem by using the reset circuit in the PIC data book (the one with 2 Rs
a cap and a diode) after this I had no problems at all with start up.
(before I had been using a simple pull up R and PWRTE enabled)
