I'm trying to adapt the 16c84 programmer (described in
the Microchip's application note AN589) to program the 16c73,
but it doesn't work.

        I have successfully programmed the 16c71, as well as the 16c84
but not the 73. The programming specifications for the 71 and 73 are
the same.

        What I'm doing wrong ?

Note: The 73 I want to program is a "PIC16c73 /JW 9526SAT" UV erasable.

        Thanks.

Ismael.
