In 1997/1998 when my only Linux box was a 386SX with Hercules, I played
around with graphics, since I wanted to view pictures.
I disturbed a lot of people with questions and could eventually display PCX
pictures (I converted all pictures I wanted to PCX using Image Alchemy)
on my Hercules screen.
I am sending the code to Greg and anyone else asking for it.
Almost no asm though (only a couple of instructions) the code is in C.
It does not compile, since I messed something up, but the functions shows
what and how to do.
I am particularly proud of the tightly coded PCX-reader! :-)
