A few points I missed:-

Commodore use their own video controller.
Interrupts are a major feature in the video (raster,collision etc.)
There is collision checking,(background and foreground plus a possible
foreground colour that is transparent for collisions).
The sound chip (SID) has a (maybe more) 4 bit D to A output also.
It also has an input that gets filtered if you desire (i.e. tape).
I have had 48 24*21 sprites on the screen at the same time.
The c64 has three Forth compilers available at my last count, plus
one full Pascal implementation.
