	If anyone out there has any knowledge about hi-res multi-color
screens produced by the Koala touch tablet, I need help!!!!
	I have a program I am writing ( attempting to...) in which I
would like for the Koala screen to be the first thing booted.  So far, I
can get the screen to load, supposedly into locations where the Koala
Painter program stores the data, but the locations confuse me.
	Using Micromon, I zeroed out all of basic memory and loaded the
Koala screen.  The only data that shows up does so between $6000 and $8800.
The *amount* of memory makes sense, 10K=2K for screen memory + 8K for data.
But the positioning of the data doesn't make sense!  Having screen memory
that high requires VIC bank switching, correct?  If so, then how does the
VIC chip see the screen on one side of the $8000 dividing line and character 
data on the other, or even the other way around?
	I have a copy of a PD program that allows you to view the screen
without loading the Koala painter program.  I have gotten and read an ML
dump of the program, but, maybe I'm dense, it doesn't help a great deal.
	HELP!!!
	Thanx in advance,

	K W Smith, Jr.
