Hey Guys,
Years ago when the earth was young (as was I), I had
a commodore 64. This system could display 4 colors in 160 by
200 pixels or 2 colors in 320 by 200 pixels. Two years ago I
purchased an IBM clone (DTK to be precise) with a monochrome
screen. Now I wish to purchase either an VGA or SVGA display
and card. But being rather confused with today's display
technology, I have decided to turn to the net for the answers
to two questions of mine.
I'm considering buying an SVGA card and screen. But,
I wish to program these in QuickC 2.5. I've looked it up and
QC does not support SVGA. Does anyone know where I can get
some drivers or libs that would enable me to program up to
SVGA resolutions?
Also, being that I only have $500 to spend on both
card and screen, should I get higher the quality card (logix
for $179) or the higher quality screen?
Thanks for any help,

The Microsoft C graphics package does not support anything above regular VGA (640x480x16), basically what you can get on a standard VGA through calls to the BIOS. You can always get a third party package (but that`s just more $$$). --Kevin

It was called "egafast" (or was it vgafast?) and was written in assembly language. It is very easy to change this thing to do any resolution up to 600x800x16 colors. It is not easy to change it for 16 colors at higher than 600x800 or for any resolution at 256 colors. Doug McDonald

I have done some programming for the Paradise VGA + in the 640X400X256
mode. ALL the information required to use this mode was provided by Paradise.
The one problem I found was a bug in the _Setpalette function provided with
QuickC, I had to write my own with in-line assembly language. If you get
one of the books available on VGA programming it will give you the info
you need to write that part. The bug was that _Setpalette worked fine in
standard VGA but not in SVGA.( Paradise claimed it was Microsoft's bug
but who knows??)
