I'd like to find someone who knows (where I can learn) about the .IMG
file format that GEM uses...  I have a 640 x 8-color printer (Radio
Shack CGP-220), which goes well with GEM except that Digital Research
never wrote a printer driver for it (and wants $1,500 for the tools just
so I can write my own!!) .    From what I can tell, .IMG files are
substantially compressed bitmaps (with some header information), but I
can't deduce enough from them to decode them.

If anyone knows the format, or a resource where I can find it, I'll be
able to write a .IMG file printer (almost as good as a print driver),
and maybe some useful translators as well.
