- 256 colours globally available.
- Independant fore/background colours in hires modes. e.g. if an upgraded chip was released with the XEs, they could run it at 7 or 14 MHz which would be fast enough for changing colour at 320 resolution.
Having Antic/GTIA seperate didn't really impede what the overall system could do, but we have the ANx bus and GTIA also having to monitor the /Halt line to know when PMG fetches are due.
If they'd been on the one die from the outset, a lot of the real estate for that interface and "prediction" of PM fetches wouldn't have been needed and could have gone towards other functions. More palette entries being yet another on the wish list.
