Can anyone point me to info on the format for the various hex file
formats-Intel, Motorola, etc?

I'm trying to put together a set of tools for PIC development on UNIX
systems, and so far I've got apples and oranges all around.

I've got PICASM which generates two different Hex output types, PICSIM
which uses another input type, and PIC_CC, a C compiler which generates
Parallax output (which PICASM won't read).  And I have two Linux based
programming packages that I haven't tried yet so I don't know what they
want. (and don't appear to recognize the Don Mackenzie programmer).

I hope to eventually have a straight path from C compiler -> assembler
-> simulator -> programmer, all free and all with source code.

Any help is appreciated.
