The 8080 had a 16bit address bus, though; which is what I always assumed was meant by referring to a machine by it's "bit count."

- ANTSANTS 13y agoBy that logic, the 6502 is a 16-bit CPU, because it (and just about every other CPU we call 8-bit) has a 16-bit address bus. The 68000 has a 16-bit data bus and ALU, a 24-bit address bus, and 32-bit registers, but is usually considered a 16-bit CPU. I guess for older CPUs, the data bus and the ALU size are the determining factors.
