Hopefully, netland has the answers to these questions:
1. Can any of the new IBM graphics cards (Enhanced, Professional)
be resident in the same box at the same time as a regular PC Color card?
Or do they seek out and destroy each other?
2. What are the specs for the Professional card?
3. Are there any monitors, other than the IBM Enhanced monitor, that take
advantage of the increased resolution of the EGA ?
4. I have seen some postings describing problems with the EGA on an
AT running Xenix. Are there problems under DOS 3.x also (on AT or PC)?
5. Is there any software (other than GEM) that takes advantage of the
increased resolution?
6. What other cards exist that offer similar capabilities?

This has the same 640 x 350 resolution as the Enhanced Graphics Adaptor but, only 4 attributes (black, video, intense video, and blinking.) The only available software which supports this mode, however, is Microsoft Word 2.0 and Gem. There are several Princeton monitors which are identically spec'ed to the Enhanced Graphics DIsplay. > 4. I have seen some postings describing problems with the EGA on an > AT running Xenix. Are there problems under DOS 3.x also (on AT or PC)? I have an EGA with mono monitor on an AT under DOS 3.0 and it works fine. Some software (Sidekick earlier than version 1.5, IBM's own Professional Debug Facility, probably more) was set for a CGA and plays around with registers which don't exist (or have other effects) on the EGA, causing the screen to mess up, and require a reboot. However, the problems have rapidly disappeared--I have Sidekick 1.5 now which works fine, and there are patches available for the PDF. Any software which tries to do centering of the video image will probably fail. Trial and error is unfortunately the only way to be sure, but I have managed to work around any of the few problems which have arisen in the moth I've had the machine. -- /Steve Dyer {decvax,linus,ima,ihnp4}!bbncca!sdyer sdyer@bbnccv.ARPA
