Hi,

   I built a ProPic a little while ago and used it mostly for 16C84
development without any problems. Octavio was pretty helpful and suggested
adding a little capacitor to one of the data lines when mine wouldn't
program.  When I get some time I will add the production programming
options, and start on a 16C73 project I have in mind.

I will probably re-design the power supply to use a 317 for the programming
voltage instead of the 7808. This will allow me to adjust the program supply
too.

I built mine on strip board, but if you fancy designing a neat PCB for it I
would love a copy. Octavio could probably post it on his page too.

Keith.
