    Hi, Luxor

    I hope for you you didn't erase your chip before ...

    could you read the value located @ 3FF location ( last Program memory location )

    IF something different from 3FFF ... note the value preciously.

    IF 3FFF then change it to something like 3420h to 3450h ... you've lost your calibration value, and the intosc won't be very precise now ... ( use only external Xtal if precision required ! )

    not very easy to recover, but Pickit 2 ou 3 have a special recovering tool ( see around you if a friend has one ...)

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    I fought with that on, I think it was a 675, or maybe a 683, anyway I tried the JDM and the PICKit2, even tried to regenerate using PICKit2 to no avail. Then I got the PICKit1 from Bruce and it worked without a hitch. I cannot say why, only that it seems to be a programmer issue.

    on the 12f629
    should it be GPIO.0 not PORTA.0

    WILL PORTA WORK
