Hi,

We have a test jig used to program small circuit boards that use a 16C57.
We are having trouble
with the test jig because it is starting to fall to bits.  PICs are being
corrupted etc.  The guy that made
it has left and the documentation is thin.  My boss is impatient and
understandably so because there
are 1000s more boards on the way to be programmed.

Currently the test jig is based on a 68HC11, using multitasking operating
system, it is a pain to learn and
maintain, and depending how much work it is to do it with a PIC, we may
just keep repairing it.  We are
thinking of replacing it with a PIC16C87X based system, done in MPLAB
assembler.

* Is there some very well written MPLAB assembler code library for
programming PICs using PICs?
It needs to RUN on a 16C87X, and PROGRAM a 16C57.

* How do I use the ICD pins, are the tools any good?

* Microchip is doing die shrinks, which already broke our 93LC46B code.
What problems can we
expect when they shrink the 16C57?

* When are the 18CXX coming out?


Thanks,
David.
