- Is it reasonable to include a video controller co-processor like the Amiga's Copper in a 1983 design? As it happens, yes. (Wikipedia)
The same basic functionality was present in the Atari 400 and 800 as early as 1979, and gave the Atari 8-bit range (including the 5200) a lot of their flexibility.
And it's very easy to emulate those functions - as long as the video emulator respects its virtual registers, all the co-processor needs to do is write to them.
So you can set it up to switch from 32-colour mode to 512-colour mode to text mode to cell mode to Amiga-style HAM mode to Apple IIgs-style fill mode on a line-by-line basis.
Reading up on the Atari architecture I noticed a number of criticisms of Atari Basic. While the criticisms were not unfounded, the whole thing fit in an 8k ROM cartridge. "Hello, world." doesn't fit in 8k these days.

This is a tactical expansion that lets you land, leave your ship, and shoot the bad guys in person.

- I forgot that this little beastie existed.
That is the HP Series 200 Model 16. Introduced in 1982, it's an 8MHz 68000-based system with 128k to 512k of RAM. It's usually seen with its dual 3.5" floppy expansion - one of the first products to use 3.5" floppies - but all the system logic is packed into that little monitor unit. The floppies reportedly ran at 600 RPM - twice as fast as normal - though I haven't found documentation to confirm that.
The screen is only 9", monochrome, and 400x300 (though text mode may have had a higher effective resolution), but that aside it was an impressive system for '82. It was not, of course, cheap, starting at around $4000.

And games actually did it, too. I remember reading about the technique in ANTIC magazine.

The 68010 and later chips fixed this.
