"The X2 I mentioned is the RB2- RC2 without ISP and PCA but it cost 1/4 as much."

I need the PCA for this project, but this is good information for the future, thanks.

"The method Jay describes only require a chip such as MAX232 and a couple of capacitors"

Believe me, I know the ISP feature is really cool and I'd like to use it, but the hardware design is finished and the prototype boards have already been assembled and conformal-coated. It's too late to make any changes to support ISP, so I'll just have to be thankful to the clever person who invented the ZIF socket. ;)
