OMG!!!  How many different programmers have you built by now?
I think it's time you used the good old "Neil Programmer" and
be done with the programming problems once and for all.  The
best part is that the Neil programmer requires absolutely no
parts, and does not care what type of port you have on your
computer, but does take a little longer to program.

If you're still interested, here are the details.... simply
place your pic in an envelope, with a return envelope as well
and mail it to me.  I'll program it and return it to you at
no charge!

Cheers,
-Neil.
