	  To acsses GR BASIC's screen ram under the kernal ($e000-$ffff), you must
first bank out the kernal (HIRAM). Too bad BASIC cannot function without the
kernal installed! You will need machine language for this task. Copy the
information to a "safe" area of memory.
	  Alternatly you could save the screen to disk, and reload it when you
want hardcopy. While this will take a lot of extra time on the 1541, it
may just be the easiest way arround the problem.
