The 6502 wasn't pin-for-pin compatible, but the bus and control structure was essentially the same, was it not? Could you, with an adapter, switch a 6800 system to a 6502, or vice versa? And what would be the details of that? (Looking at the Apple 1 may help you with this.) | |

E.g., zero-page (8-bit) addressing as an adjunct to absolute (16-bit) doesn't depend at all on whether the CPU is being used to control an car or as a general purpose computer. | |
