Gregg,

It is starting to be a little dated now, but you can download the
documentation for my PP1 programmer. It has a chapter on ISP and what I
know about it back then. You may find the knowledge contained of value,

It is in the FTP section of my web grossly neglected web site at.

Feel free to pick my brians (within reason) or even to buy one of my
programmers (says me very squeamishly...) :-)

Jim
