Don't forget the built-in MIDI.

The inverse color scheme? Not so great... which people are finally admitting 40 years later.

Not sure it was so, but it'd be interesting if the monochrome mode used two entries of the palette. Possibly also easier to implement as well.

That's how it was. Flipping to inverse as really easy and there were lots of auto programs or desk accessories that included an option for it, including I believe Atari's stock control panel.
