It is not way to slow to run graphical applications damn you! :-) (offence not
intended). I have used a herc card on an XT for ages. It is slow in compasion
to todays machines but I ran many graphical applications

Could i get them :) The herc card was my favourite (a long time ago)

Ok, i don't have any examples, but I once write a assembly line draw. It uses a
direct buffer (32K) which has an vertical interleave of 4 which complicates
things. Horizontal lines are easy. Vertical lines are somewhat less easy but
still no problem. If you want me to optimised asm routines for the herc card
tell me. :)
