I am interested in writing applications which can use EGA graphics on a
PC-AT which runs Microport System V UNIX.  Although Microport provides a
driver, it provides only the lowest level of support requiring an
application to execute many calls to perform a simple graphics function.  I
suspect performance problems would surface using this interface, although I
am not sure.  In any event, I am looking for an alternative.  Although the
bios associated with the EGA card contains some higher-level support, it
cannot be used with System V  (this information comes directly from
Microport).

Has anyone written an application for EGA in this environment?  If so, how
did you do it?  Alternatively, does anyone have any knowledge of a workable
approach to this problem?
