Hi,
Does somebody here know the formulas for calculating the offsets and
bits in the CGA memory? Or maybe a quick routine for plotting a pixel?
The BIOS routine sure seems SLOW to me. I'm experimenting with these
older machines, so I'm working a little with these cool graphics
cards! (The CGA is great! Well, I LOVE IT! :-) )
Ciao,
Lionel
You might see if you can find "A Programmers Guide to PC &
PS/2 Systems" Richard Wilton ,published by M-S Press. Came out
in 1987 and received rave reviews in all the trade publications. It
has ass. routine listings to access BIOS for CGA thru VGA and a
wealth of other info on the varios Dos video systems.
