  I have figured out how to activate/deactivate the 80 column card without
even touching the softswitches...  Its a lot neater anyways..

  1st, check the machid byte (bf98) and make sure they have an 80 column card,
if they don't, then they cant use 80 cols..  otherwise, to turn 80 cols on,
simply do a jsr to $c300, and to turn the 80 col card off, simple lda #$15
then jsr $c300...
  Of course, I figured it out a few hours after I posted the message..oh
well..

  But now, I need to now how to to a HTAB in ml..  I've figured out how to do
a vtab by looking through the old apple ][ reference manual, but I couldn't
find any mmonitor routines which would do a htab for ya..

   any help would be greatly appreciated..
