The MOS Technology 6510 is an 8-bit microprocessor designed by MOS Technology. It is a modified form of the very successful 6502 . The 6510 is widely used in the Commodore 64 (C64) home computer and its variants.
One popular 6502-based computer, the Commodore 64, used a modified 6502 CPU, the 6510. Unlike the 6503–6505 and 6507, the 6510 is a 40-pin chip that adds internal hardware: a 6-bit parallel I/O port mapped to addresses 0000 and 0001.
The CSG 65CE02 is an 8/16-bit microprocessor developed by Commodore Semiconductor Group in 1988. [1] It is a member of the MOS Technology 6502 family, developed from the CMOS WDC 65C02 released by the Western Design Center in 1983.
8500 – CPU HMOS-II Version of 6510; 8501 – CPU HMOS-II 6502 with 7-bit I/O port; 8502 – CPU compatible with 6510 but able to run at 2 MHz; 8520 – CIA (Complex Interface Adapter) 1 MHz 8520 or 2 MHz 8520A-1 in Amiga; 8551 – ACIA Asynchronous Communications Interface Adapter, HMOS-II variant of the 6551; 8562 – VIC-II (NTSC)
The original 6502 has 56 instructions, which, when combined with different addressing modes, produce a total of 151 opcodes of the possible 256 8-bit opcode patterns. The remaining 105 unused opcodes are undefined, with the set of codes with low-order 4-bits with 3, 7, B or F left entirely unused, the code with low-order 2 having only a single ...
The methods by which the MPU state is preserved and restored within an ISR will vary with the different versions of the 65xx family. For NMOS processors (e.g., 6502, 6510, 8502, etc.), there can be only one method by which the accumulator and index registers are preserved, as only the accumulator can be pushed to and pulled from the stack.

The 6507 (typically "sixty-five-oh-seven" or "six-five-oh-seven") is an 8-bit microprocessor from MOS Technology, Inc. It is a version of their 40-pin 6502 packaged in a 28-pin DIP, making it cheaper to package and integrate in systems. [3]
GeckOS is a multitasking operating system for MOS 6502, and compatible processors such as the MOS 6510. [1] The GeckOS operating system is one of the few successful attempts to implement a Unix-like operating system on the 6502 architecture.
