Image of the internals of a Commodore 64 showing the 6510 CPU (40-pin DIP, lower left). The chip on the right is the 6581 SID. The production week/year (WWYY) of each chip is given below its name. The MOS Technology 6510 is an 8-bit microprocessor designed by MOS Technology. It is a modified form of the very successful 6502.
A technical drawing displaying the pin configuration on a en:MOS Technology 6510 Central Processing Unit (CPU). This en:SVG file was created by me, en:User:Crotalus horridus , in en:Notepad . The en:MOS Technology logo is assumed to fall under fair use (for illustrative purposes), but if it is not, it can easily be removed from the vector list.
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 ...
Image of the circuit board of a Commodore 64 showing some important MOS Technology circuits: the 6510 CPU (long chip, lower left) and the 6581 SID (right). The production week/year (WWYY) of each chip is given below its name. The 6502 was so cheap that many people believed it was a scam when MOS first showed it at a 1975 trade show.
The category of 65xx microprocessors consists of articles about MOS Technology's venerable 65xx family of 8-bit processors, as well as compatible 8/16-bit developments of the architecture by other companies.
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.

Technical specifications [ edit ] The CPU named CSG 4510 R3 is a custom CSG [ 5 ] 65CE02 (a MOS 6502 derivative), combined with two MOS 6526 complex interface adapters (CIAs), a UART serial interface, and a memory mapper to allow for an addressable space of 1 MB [ 6 ]
MOS Technology 6508 pin-out. There may be different strapping/bonding variants of this chip; the datasheet below lists pin 40 as clock phase two, but in the CBM900 computer, the 6508 controlling floppydisk has pin 40 as "Set Overflow" (SO). SO is a pin that is also offered on the 40-pin 6502, but omitted on all the 28-pin 650x variants (6503 ...
