I didn't think that video memory had to be allocated; i.e. the extra 16k is
already there somewhere.  Am I wrong on this?  It is still at $b800, isn't
it (unless you specicfically set otherwise)?

I know for a fact that Microsoft QuickBASIC does NOT support them - tho
it supports most everything else.  Oh, well.

Please add me to the list of people interested in any more info that comes up!
