   ok, mine has one serial port, and no graphics or attributes.  also,
after formatting a double sided kaypro floppy on my AT with uniform,
the kaypro claimed it was a single sided floppy, so apparently it has
single sided drives.   would i need to change the bios to add double
sided drives??  (i'd like to put qd drives on it, or better yet, 1.2
meg AT floppies by faking the controller to think it's talking to
an 8 inch drive, if that's possible.  is there a rom available that 
would allow 8 inch drives to be connected to a kaypro??
 
   also, what is needed to upgrade the video to the 84 standard??
i use vde as a text editor, and it need reverse video to show
control characters.

   also, how do you tell if the machine has a IV motherboard???  if
mine does, then i could probably get dsdd or qd drives to work
in it.
