The 68030 is also a 32-bit processor with 8 general purpose registers. The 6502 is an 8-bit processor with one accumulator and two index registers, though it could use the first 256 bytes of memory (zero page) as pseudo-registers.

Yes, although the zeropage is quite cramped. There's only about 8 bytes free there if you don't want to overwrite anything. Accessing the zero-page only gains 1 cycle out of 4 needed to access non-zero-page memory locations, anyway, so that's only a 25% performance gain in very limited applications.
