Well, then I might as well point out, that IBM did make a 8-bit adapter for VGA, so I could use my Sony Trinitron with my PC XT 10Mhz clone. Beat the daylights out of my roommates 6Mhz AT, and ran Xenix, which most unfortunately turned me into a Xenix expert of crap ware. After a bad compile, it destroyed both drives file system, so I went back to just Windows 1.0.6, and DOS.
The IBM PS/2 Display Adapter was a confusingly named 8-bit ISA VGA adapter. The PS/2 in the name referred to the fact that it allowed your prior generation machines to run the same graphics system as the PS/2 line.
Young uns... I personally had a 286 with VGA back then...
