Deluxe Paint was even written for this unit. I saw a screenshot not long ago, though I can't seem to find it online right now. It seems a similar concept to the Apple IIgs (in relation to the Mac, as this is in relation to the Amiga). Its CPU is a ~4MHz 65C02, while the GS had a more powerful 65C816, but the graphics chip in the C65 is likely far more powerful than that of the IIgs.
An interesting unit. I'd enjoy one.
