This is only part of the story. The are problems that are keyboard/rom
related as we have code(KERMIT) that uses the extended INT 16H functions and
still fails to return keycodes. This happens on a Zenth 286LP but not various
PS 2 models or on other Zenith models. Don't know the solution but hope 
someone out there does.  We are also trying to get info from our local 
Zenith rep.
