The MOS Technology 6510 is a 8-bit microprocessor designed by MOS Technology, Inc., and is a modified form of the very successful 6502. The primary change from the 6502 was the addition of an 8-bit general purpose I/O port. In addition, the address bus could be made tristate. The 6510 was only widely used in the Commodore 64 home computer and its variants. In the C64 the extra pins of the processor were used to control the computer's memory map by bank switching, and in the C64 also for controlling three of the four signal lines of the Datassette tape recorder. It was possible, by writing the correct bit pattern to the processor at address $01, to completely expose almost the full 64KB of RAM in the C64, leaving no ROM or I/O hardware exposed except for the processor I/O port itself.
