When learning how the screen RAM load save worked it occurred to me

I actually used those unsed RAM locations in the far right two LCD
controllers with ASCII Pixels. I use them when displaying the "cursor"
to save the LCD contents prior to drawing the cursor, then when the
cursor moves, I restore the original LCD image (that was destroyed by
displaying the cursor) from the data stored in those unused RAM hidey
hole locations.
