The MOS Technology 6502 (typically pronounced "sixty-five-oh-two" or "six-five-oh-two") [3] is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of ...
It is a member of the MOS Technology 6502 family, developed from the CMOS WDC 65C02 released by the Western Design Center in 1983. Like the 65C02, the 65CE02 was built on a 2 µm CMOS process instead of the original 6502's 8 µm NMOS technology, making the chip smaller (and thus less expensive) as well as using much less power.
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.

To start the process, the game program running on the MOS Technology 6502-based CPU loads the TIA's registers with the data needed to draw the first line of the display. The TIA then waits until the television is ready to draw the line (under the command of the TIA's associated analog hardware) and read out the registers to produce a signal for ...
MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor), later known as CSG (Commodore Semiconductor Group) and GMT Microelectronics, was a semiconductor design and fabrication company based in Audubon, Pennsylvania. It is most famous for its 6502 microprocessor and various designs for Commodore International's range of home ...
In addition to being manufactured by MOS Technology, the 6522 was second sourced by other companies including Rockwell and Synertek. The 6522 was widely used in computers of the 1980s, particularly Commodore 's machines, [ 1 ] and was also a central part of the designs of the Apple III , Oric-1 and Oric Atmos , BBC Micro , Victor 9000/Sirius 1 ...
