I expect that all of the TTL latches and glue logic could be incorporated
into a single PLA/PLD by now, but the 6502/65816 core probably still
requires a chip all by itself.  The most efficient design would probably
require 4-5 chips including:
- PLA or PLD for glue logic and latches
- CPU (e.g. 65816)
- Memory module (e.g. an 8 Meg SIMM)
- 1 or 2 analog interface chips
