The Atari 5200 and 800 are capable of 320x200 in 2 colors, or 160x200 in 4 colors - and the screen layout is a typical bitmap - so it should be easy to use...

Unfortunately, setting it up is hard - we need to define a 'Display list' which configures the screen layout, and the A5200 and A800 have graphics hardware at different memory locations!... Lets learn how to make it behave!
