  The following memory map is pure speculation:

  0000-01FF     R/W		RAM

  0300-03FF     R/W		RAM
  0400-07BF		R/W		Video RAM
  07C0-07FF		R/W		Sprite RAM
  1000			W		???
  2000			W		???
  2001			W		???
  2003          W		Start LED 1
  2004          W		Start LED 2
  3000			R		$40 = !UP			$80 = unused?
  3001			R		$40 = !DOWN			$80 = ???
  3002			R		$40 = !LEFT			$80 = ???
  3003			R		$40 = !RIGHT		$80 = unused?
  3004			R		$40 = !START1		$80 = ???
  3005			R		$40 = !START2		$80 = !COIN
  3006			R		$40 = !BUTTON1		$80 = !COIN
  3007			R		$40 = unused?		$80 = !COIN
  4000          R		???
  6000-600F		R/W		Pokey 1
