Hi John,

        I'm in the same boat, and have come to the same conclusion.
I'm using Kevin's software with a Warp-3 programmer. It will program
the 'F8xx parts by setting it for an 'F84 part, but is not able to
get the 'F8xx parts out of LVP mode, and will only allow the 1st 1k
words to be programmed.

        How about another, perhaps not so sophisticated, but, open
source enough to modify, assembler/programmer for the Mac. All you
have to do is build a very simple board with an 'F84, and learn  some
HyperCard.

        http://www.execpc.com/~fdeck/mac/               <- web page

        http://www.execpc.com/~fdeck/mac/pic203_install.sea.hqx <- file url

        The file contains a documentation file with schematics for
the programmer, PIC Assembler/Programmer HyperCard stack, and
firmware listings for the 'F84. The HyperCard stack software is all
accessible if you have the HyperCard software. If you have just the
player then Francis has included a handy button that prints all the
scripts, but you won't be able to modify them,
Which will be necessary.

        My thoughts are to learn enough about hypercard to modify the
configuration parts to allow for the more sophisticated configuration
options of the 'F8xx parts. The other feature built into Kevin's code
is a memory limit check. Since Francis' doesn't have this check it
doesn't need to be modified for the additional memory of the 'F8xx
parts.

        Now I haven't built the programmer, and not used the software
but it all seems doable.

This may be the solution your looking for,
Heinz
