I just checked the data sheet on the 876 (is everyone proud of me! :-)

Using the bootloader and a MAX232, I am using high voltage programming? Yes? and the PGM pin is associated with Low Voltage Programming and In-Circuit Debugging. So I think I am ok there.

I DID however find a major problem.

Yep... I did it... I think I read the drawing of my 9-pin D-sub in reverse... all of my pins on the board are mirrored. :-P

SOOoooooooo... I think I found my problem. Wierd that it should give me almost all of the same voltages on the MAX232 pins except one. ???

I'll yank the D-Sub and flip it to the other side of the board and see if that cures my ills.

Will get back shortly.

The amateur in me is showing. :-)

Thank again!
