1. WDC 65C02 - An enhanced, low-power version of the original 6502.
2. Rockwell R65C02 - Another variant offering additional instructions and improvements.
3. MOS 65C02 - A CMOS version with extended features over the original NMOS 6502.
These chips share similar architecture and can often be used interchangeably in applications designed for the 6502 family.

The R652106, commonly referred to as the Ricoh 2A03, is an 8-bit microprocessor used in the Nintendo Entertainment System (NES). It integrates a CPU and an audio processing unit. This custom version of the MOS Technology 6502 has 40 pins. The pin functions include:
- Power and Ground: VCC and GND pins for power supply.
- Address Bus: 16 lines (A0-A15) used to address memory.
- Data Bus: 8 lines (D0-D7) for data transfer.
- Clock Inputs: M2, to determine the operation speed.
- Control Signals: Including R/W (Read/Write), IRQ (Interrupt Request), NMI (Non-Maskable Interrupt), and RESET.
- Audio Output: Two pulse wave outputs, triangle wave, noise, and DMC (Delta Modulation Channel) for sound synthesis.
- I/O Ports: Two ports for connecting peripherals like controllers.
The R652106 is central to the NES's operation, handling both game logic execution and audio generation.
