One of my coworkers has 100 PIC OTP's which he attempted to secure using the
BP Microsystems' Programmer's "secure" option after he programmed them.  Unfor-
tunately, that option burns the entire configuration word to zeroes including
the oscillator type (making it LP--it should have been XT for use with a 4MHz
crystal).

Is there any easy way to hack the oscillator circuit (tack-soldering on com-
ponents as needed) so that an LP-programmed PIC will operate at 4MHz?  Someone
earlier suggested that the oscillator fuse option controls the feedback resist-
or; would adding a resistor between the OSCIN and OSCOUT pins make the LP parts
behave like XT parts, or are the only reasonable options at this point to:

[1] Tack on an oscillator module (pricey, and probably not worth doing), or

[2] Slag the chips and reburn them properly.

I suspect #2 is the only real option, but if anyone else has any better ideas
it'd be appreciated.
