Does anyone know how to access the VGA board on a IBM Model 80 from C?

Buy Turbo C from Borland, their new graphics routines are great!

I have MSC 5.1 which includes a graphics library that does handle VGA (as well as EGA, CGA, etc.). I don't know if any earlier versions of MSC had this capability.

MSC5.0 has quite a few graphics routines and has access to all the standard IBM video controllers. I suggest you call them and get the standard brochure for 5.1. The one I got had a list of all available functions (everything, not just the graphics). ------------------------------------------------------------------------ Kurt J.

I did a program that used the MCGA mode on the model 60 and it worked just fine (and it was very easy to write because the library routines are extremely simple). There are two caveats though, you must have either version 5.0 or Quick C (the real documentation for the graphics routines are in chapter 4 of the Quick C manual, fortunately that comes with 5.0 also). The other caveat is that you can forget using any of the fancier modes on the new Super VGA cards with the Microsoft library, if you want to use those you'll just have to get down and dirty. However, this shortcoming probably affects the Turbo libraries also :-( John Munsch

Craig:
I presume you mean low level access to the chip set rather than
simply calling the BIOS routines. is this correct? If so, it
becomes much less a 'C' problem than a doc problem on the card
itself. I don't have any info on that specifically, but I might
suggest you call someplace like the Computer Literacy Bookstore
in Sunnyvale, California. They know computers and know the
available books: they also mail order I understand, although
I am a local so I've no direct proof of that. Once you have
the chip stuff, it should be easy to define some memory variables
and play to your heart's content.
