	WDC 65C02 - Wikipedia, the free encyclopedia
		The WDC 65C02 8-bit CPU is an upgraded CMOS version of the popular and venerable MOS Technology 6502 microprocessor, the redesign being made by Bill Mensch of the Western Design Center (WDC).
		The 65C02 was second-sourced by NCR, GTE, Rockwell, Synertek and Sanyo.
		The 65C02 shared its predecessor's 8-bit instruction set architecture and 16-bit memory addressing, but added a small number of documented opcodes and, significantly, fixed the irksome "indirect jump page wrap bug" that caused fits for so many budding assembly language programmers.

		Design work for the chips was completed in November 1981, but the console project was soon cancelled after a meeting with Commodore president Jack Tramiel.
		Designed by Jeri Ellsworth, a self-taught computer designer who had earlier designed the modern C-One C64 implementation, the C64DTV was similar in concept to other mini-consoles based on the Atari 2600 and Intellivision which had gained modest success earlier in the decade.
		So while accelerators based on the Western Design Center 65C02, usually running at 4 MHz, and on the 65816 at up to 20 MHz appeared, they appeared too late and at a price of US$199 or higher were too expensive to gain widespread use.

	Apple II History Museum - Articles
		Western Design Center (WDC) and its founder, Bill Mensch, played a critical factor in the development and release of the Apple IIc and IIgs.
		It was Mensch who spearheaded a re-creation of the 6502 processor into the lower-powered 65c02, which included the additional assembly language opcodes that made it possible to "crunch" the ROM code in the Apple IIc small enough to fit in its additional built-in functions without excessively complicating the design or coding.
		In 1983, WDC extended the architecture of the 65C02 to 16 bits with the 65C816, which was used in the Apple IIgs.

		In January 1981, MOS Technology, Commodore's Integrated circuit design subsidiary, initiated a project to design the graphic and audio chips for a next generation Video game console.
		The design team was given less than two months to develop a prototype so that it could be displayed at the winter Consumer Electronics Show in January 1982.

		All of the bank select registers, etc., from the 65816, are still intact in the 65802 CPU core, they just have no effect when used.
		Typically, when hardware manufacturers have designed a project from the ground up, they have used the more powerful 65816.

		It was designed as a single chip version of the TI 990 minicomputer series, much like the Intersil 6100 was a single chip PDP-8, and the Fairchild 9440 and Data General mN601 were both one chip versions of Data General's Nova.
		The R2000 design came from the Stanford MIPS project, which stood for Microprocessor without Interlocked Pipeline Stages [See Appendix A], and was arguably the first commercial RISC processor (other candidates are the ARM and IBM ROMP used in the IBM PC/RT workstation, which was designed around 1981 but delayed until 1986).
		A design typical of many load-store processors, the PA-RISC (Precision Architecture, originally code-named Spectrum) was designed to replace older 16-bit stack-based processors in HP-3000 MPE minicomputers, and Motorola 680x0 processors in the HP-9000 HP/UX Unix minicomputers and workstations.

		As far as 6502 instruction set extensions go, the ones I'm aware of are: 1) WDC 65C02 family 2) Rockwell bit set/clear/test instructions - x3/x7/xb/xf opcodes (maybe on GTE 65SC02 as well?) The Rockwell 65C02 family has these as well as the WDC 65C02 instructions.
		Has a subset of the WDC 65C02 extended instruction set, but with different opcodes 5) Mitsubishi 37700 family - 16-bit extension similar to the 65C802/816 but not fully compatible And of course there was the processor in the Nintendo NES, which was basically 6502-compatible but without decimal mode.
		Commodore Semiconductor (formerly MOS Technology, developer of the original NMOS 6502) apparently designed their own CMOS 6502 core that was not 100% compatible with the WDC part and its clones.
