Yeah, i tried programming once, and when that didn't work, i have been
just trying to verifiy.

I have been probing the signals to look at them, and the difference i
see when i verify with the chip in and out is that the VPP and VDD
signals do have trouble at first because of the capacitor i have on the
output of my 5V regulator.

Someone mentioned the drive ciscuit in MC's ICSP book. I just found that
circuit last night, and will try to build it today or tomorrow. I'll let
you all know if it works.

Thanks everyone for your help!
