I have a crash project to write a graphics program in Turbo C on a 286
with a VGA card. I have already done much C graphics programming on
other hardware, but am mystified by the complexities of VGA cards. I
am hoping to get some answers to specific questions. (The project
simply involves drawing geometric shapes of different color and doing
animation.)

1) How do you set colors lookups? (All those different registers are
crazy! Who designed this thing anyway?!)

2) How do you plot on different pages and do page flipping.

3) Is there some way to catch the video sync pulse (for page
flipping)? Is there someway to send out a signal from the sync pulse?

4) Is there some PD software to make life easier.
