I had a weird experience last nite...... here goes. I
completed building my ICD2 clone. Fix the stability
with RS-232 communication and made SURE that the
target had 4.5-5.5 for operational mode and 13v for
programming. But the biggest mystery is it did not
detect my PIC 16F873A chips........ 

MPLAB reported that it could not detect the uC device
id........ Fortunately it detected one of my PIC
16F873A chips......... The only difference was that it
was programmed on my PICStart Plus. After placing my
OTHER chips into my PICStart Plus and erased it then
my ICD2 started to recognize the chip and started to
program it............ prior to that I may have not
applied the correct voltage sequence to my other
chips.  Any clue on this mystery? it looks like ICD2
needs a device id which sounds sensible but WHY in the
first place did my chip's id GO MISSING?????


Thanks,
John

To tired to think creatively for an answer.zzzzzzzzz...........
