I need to program the AT&T 6300 graphic card in the 640 x 400 mode and
had little luck.  The documentation I have is internally inconsistent.
To be specific, I need to have the correct bit settings on the two mode
select registers hex 3D8 and hex 3DE.  The AT&T Tech Ref Menu said one
thing at one place and another on the summary page.  I have tried
both and none of them work.  If someone can give me a hit, I will
greatly appreciate the help.
