I just started working on modifying the software this week, but I'm having
trouble getting it to compile. The problem is in the conio.h header. I've
tried Miracle C, a shareware compiler, and Plato, the C compiler we have on
the university network here. The other problem is my C programming is very
rusty, I haven't done it since my undergraduate graphics course, which was
more than five years ago. I've had to get a couple of books out of the
library to brush up a bit.

CMASK is the mask for the configuration word. On the 16C84, the config word
only uses the first 5 bits (I think) so thats why it is 001Fh. On the other
supported processors, the 16F83 and 16F84, they use all 14 bits, so it is
3FFFh. The 16F628 also uses all 14 bits.

IMASK I'm not sure about either, I'm still trying to figure that out. But
for the most part, it seems fairly straight forward. Just increase PSIZE,
PSIZEMAX, DSIZE, DSIZEMAX to the values for the 16F628. Anyone know what the
ISIZE and IMASK are for? Something to do with interupts I'm guessing.
Unfortunately I program in Pic Basic, so I don't really work with the PIC
architecture directly. If I did, I'm sure it would help.
