I recently purchased a used HYPERION Portable PC which is suppose
to be IBM compatible. All works well until I try to run "graphic"
programs (e.g. Microsoft Windows, Flight Simulator, Trivia, etc.).
These programs display their initial graphics just fine, but the
keyboard is "dead" after they load. Seems like the software is
generating a keyboard interrupt. With most of these programs, I
have to turn the power off/on to reboot DOS. With Microsoft
Windows, the keyboard appears "dead", but will allow a ctrl-alt-del
reset.
The problem seems independent of the DOS version I am running. I
get the same results with version 1.25, 2.0, 2.1, and 2.11. The
HYPERION reference manual indicates that the interrupt structure
is identical to the IBM-PC. Most of the IBM CGA programs I have
tried seem to "run" okay.
I sure would appreciate some feedback and any suggestions on how
to resolve this problem.
