8 BIT CPU
MOS Technology 6502 processor are a family of inexpensive
8-bit microprocessors. 6502 processor could address 64KB
of memory, other CPUs in the family could address up to 8 KB.
Stack size of the 6502 was limited to 256 bytes.
The processors had only 6 registers, and only one of these registers -
an accumulator - could be used for arithmetic and logic operations.
The 6502 microprocessor had 13 addressing modes, some of these
modes made extensive use of two 8-bit index registers.
The processor didn't have I/O instructions, therefore 6502-based
computers used memory mapped I/O.
