One of the drivers in GEM that I've never been able to test is for an
'MDSI Genius' card. Tonight I tried patching support for this card into
a PC emulator, and running GEM (and Windows 1) with the results.

According to reviews, the card could also do other tricks; it could
superimpose MDA-style text on the graphics output, and do a dual-head sort of
display with MDA text in the top half of the monitor and CGA graphics in the
bottom. But without any documentation or its DOS driver (VHRBIOS.SYS), how
it did those will remain a mystery. Such information as I have managed to
glean is at <http://www.seasip.info/VintagePC/mdsi_genius.html>.
