No Nigel Goodwin's software will only do 84's, but very nicely.
I have spoken to Nigel recently about catering for the F84, however I
think all he really needs is a device to try.

Ken Segler's software last count, didn't cater for the two code protect
bits. I sent him Email about this a long time ago, but haven't heard
anything back. Still with us Ken?

Octavio Nogueira (TATO Computers) last time I looked, didn't support it
either, however I think he has some 'A' parts support. Perhaps he will
reply to this and update us.

Antti Lukats (SiStudio) doesn't support it yet in his PIP02 driver. Rest
assured I have prompted him about this and the F84 support.

I know that the 'A' parts are gradually replacing the old versions. I
can no longer get non-'A' PIC16C74/JW parts.

I wonder if the same thing will happen with the C84.

Sorry I couldn't give you anything positive on the Davit Tait type
programmer software upgrades. Perhaps someone else can. Maybe even David
knows. :)

As new devices come out, you can rest assured the saga will continue. :)

you will find the wiring of the header to the 28 pin socket.
Also the combination of my DT.001 board, (updated PIC84PGM) and a
PIC.003 SimmStick board will do this job for you.
