    I'm trying to program/debug an 8 pin PIC12F509 (8 pin version with 8
    DIP packaging) with the AC162059 header. The MPLAB IDE claims that the

    chip is there, and I try and program it and it all claims that it was
    sucessfull...when in fact the pic wasn't even in the socket. Also, it
    seems to "simulate" the chip wihout the chip in there. When I try and
    download the file registers while in debug mode there is a bunch of
    garbage. Another thing is when I program it and click "verify" the
    MPLAB claims that the chip is correctly programmed (again with no pic
    in the socket). Also it seems to remember it I erased the chip or not
    and will indicate wether or not it is blank as if there was a PIC in
    the socket...all of course without anything in the socket. Is this
    thing busted or am I missing something fundamental. Perhaps it's the
    way this thing operates. Also, when I place the PIC in the
    socket...the voltage on the positive pin goes way too low. This is all

    while I have the 9 volt additional power plugged in. And, also I get
    this error no matter what operation I'm doing...and even if the chip is

    in there...:

    "ICDWarn0044: Target has an invalid calibration memory value (0x0).

    Any ideas?
