You'll probably get several arguments to that one. To read mine check out:

Well for software I highly recommend David Tait's FPP:

http://www.man.ac.uk/~mbhstdj/piclinks.html

With the addition of a single DLL, operation on XP has been verified.

My programmer, the TLVP doesn't meet your requirements. It's here:

http://www.finitesite.com/d3jsys

It's deliberately designed as a trivial low voltage programmer. Works great
on 16F87X and 16F62X parts in low voltage programming mode, but won't work with
the 16F84A, which requires high voltage.

I belive you'll save yourself a lot of headache if you shelf the 16F84A and
step up to the newer offerings. It also simplifies the programmer and widens
your possible choices.

Hope this helps,
