Resolution and palette are often used as substitutes for one-another when
displaying images, as any MAC or hi-res ST user can tell you.

Though some places you can't buy anything except a PC.  There are actually
aftermarket 68000 boards that fit in a PC case and replace the ENTIRE
motherboard.  That's so engineers, etc., can get the order for a PC through
purchasing, and the 68000 board as simply an "add-on".  The suits are wasting
too much money with the IBM-only attitude; hopefully that won't last much
longer.

I've been working with 8-bitters too long not to appreciate it.

The Amiga could easily use either Motorola 68000 family MMU, or a custom
MMU, if hardware protection is required.  And a 68010 would really help
things along.
