Robert is right: it's hardly an obscure trick. The "Windows" package
that someone donated to our public software archive in 1983 worked this
way. More recently, the DOS version of the "JWindows" packages also used
direct hardware access. ("JWindows" also supported "high resolution"
graphics screens (i.e. VGA) with 50-line windows.)

But none of that works on Windows NT or 2000, and most of it only works
in DOS mode on Windows 95 or 98, making it too obnoxious to use even on
those systems.
