PD CGI functions

[root]

Does anyone know of a Public Domain version of SCO's
Color Graphics Interface routines. Or a set of functions that
will handle bit mapped graphics on a VGA (or C/Ega) monitor?

I've read their documentation and it seems to be a lot more
complicated than necessary... plus it dosn't appear to handle
VGA mode.  This is for a 286 running 2.3 OS.
thanks in advance....
