Comments from Paul Leaman:
230+
The graphics are all stored in planar format with 4 bits per pixel. The
231+
graphics appear to be organised in 4 separate banks of memory. There are
232+
2 banks with two planes per bank for the left half of 16x16 tiles and 2
233+
further banks for the right half of the 16x16 tiles.
234+
235+
The graphics are very flexible. You aren't restricted to set numbers of
236+
characters, tiles or sprites. This makes it a perfect system for developing
237+
new games.
238+
239+
There is a lump of video RAM that holds the sprites, palette, scroll 1,
240+
scroll 2 and scroll 3. The actual base adresses of these areas within the
241+
video RAM are controlled by registers. By altering the base addresses, it
242+
looks like you can double-buffer sprites etc.
243+
244+
There are a set of output registers that control the scrolling and base
245+
adresses of the video RAM and various layer priorities etc.
