Tonight I tried patching support for this card into a PC emulator, and running GEM (and Windows 1) with the results. <http://www.seasip.info/Gem/History/longgem.png> - GEM/2 desktop <http://www.seasip.info/Gem/History/longwin1.png> - Windows 1.04 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>. -- John Elliott _______________________________________________ gem-dev mailing list gem-dev at simpits.org http://www.simpits.org/mailman/listinfo/gem-dev
