	WDC 65816/65802 - Wikipedia, the free encyclopedia
		The WDC 65816 (also: 65C816), a 16-bit microprocessor CPU developed by the Western Design Center (WDC), is an expanded and compatible successor to the venerable MOS Technology 6502.
		The WDC 65802 (also: 65C802) is a 65816 CPU in a 6502-pinout package (fully 6502 compatible).
		The 65816 was second-sourced by GTE, Sanyo and a couple of other semiconductor companies from the mid-to-late 1980s to the early 1990s.

	Apple cart; the 16-bit Apple IIx; Apples On-Line.
		The 65816 is a 16-bit CMOS (complementary metal-oxide semiconductor) version of the classic 6502 microprocessor that is at the heart of the Apple II.
		Stated quite simply, the 65816 is pin-and software-compatible with the 6502 when in 8-bit emulation mode, yet the toggling of the single flag bit is akin to throwing the throttle of a BMW motorcycle wide open and bursting into the realm of 16-bit processors.
		In theory the 65816 is entirely pin-and software-compatible with the 6502 and could actually be used in existing systems with little or no additional support hardware.

	SuperCPU Kurs - Folge 2
		While the 8500 (the processor in the new C64's) and the 8502 (new C128's) are based on the 6502/6510 processors, the 65816 is a totally new processor, a truely new development.
		The 65816 has the ability as well as the memory to switch to the 16 bit wide index register (X and Y).
		This is the strong point of the 65816 in Native mode: the switching between 8 and 16 bit modoes - an ability which is either not available on other processors, or if it is present, it is very limited.

		The 65816 is an advanced upgrade to the vintage 6502 Central Processing Unit.
		However, if you are writing Native mode 65816 code with 16 bit accumulator and/or 16 bit index registers, and you are using a stock kernal IRQ that assumes emulation mode, then you must do some coding to handle the discrepancies.
		The implications are that if the 65816 is running in emulation mode in a ram bank other than Bank zero, then the program bank is going to be lost (not good).

		Since this extra byte is present, it is essential that the RTI be executed in the same mode (e=?) that the processor was in when the interrupt was executed.
		There is a RESet B pin on some 65816 processors that allow for the usage of this instruction.
		Two new 65816 instructions are used to exchange data between the accumulator and the Direct Page Register.

		Instead of zeropage addressing modes, the 65816 has direct addressing modes, that add the contents of the direct register to the zeropage address in the opcode.
		But the 65816 behaves differently, it has a 16 bit stack pointer for example.
		For the 65816 the zeropage segment changes its meaning to a bank zero segment.

		When I met the 65816 processor for the first time, I was immediately captivated by the range of enhancements that it provided.
		The 65816 is a wonderful improvement over the 6502, containing 78 new opcodes, 9 new addressing modes, block memory moves, 16-bit registers, relocatable stack and zero-page, and a 16 megabyte linear address space.
		If you want to write a program that will run on both the 6502 and 65816 CPUs, yet take advantage of extra 816 abilities if it is present, then you need a way to determine which processor the code is running on.

		To be able to use a faster processor one has to create a small system with its own RAM which only replaces the necessary parts of the C64.
		The 65816 is the successor of the 6502 and a number of companies tried hard to put this processor into the C64.
		The big problem is that beside the 65816 there is no successor to the 6502.

		In case of the VIC-20 and other 6502 equiped computers it is relatively easy to replace the 6502 with the 65816.
		The 65816 has 24 addresslines, 4 more then the 8088 or 8086, and is capable of addressing up to 16 MB.
		Both the 6502 and 65816 use memory mapped I/O so I had to find a way to address the PC-I/O. A nice thing about the VIC-20 is that it has two reserved I/O-areas, each sized 1 KB.

		In the 6502 there is a little, far-reaching, mostly unknown glitch (don't worry, according to the rules, the processor calculates correctly!): In decimal mode (with SED turned on) the Negative-Flag gets set incorrectly.
		This happens because the 65816 correctly calculated that the result is zero (a positive word).
		Caution: There are some old turbocards for the C64 which use the 65816 processor, but they don't have nearly as many good qualities as the SuperCPU.

		_Professional_ developers, to my knowledge, use a PC and a special 65816 assembler called SNASM which assembles and allows debugging of 65816 code, also included is a device which (I believe) plugs into the SNES and you download code from your PC to the SNES through a SCSI interface.
		People download their own code to these devices using 65816 cross assemblers (apparently availabe to most major platforms), and the SNES runs it.
		You have to have a pretty good knowledge of the SNES hardware, and of course be an expert 65816 assembler.

		At 5V, the 65816 is still rated for only 14MHz, but some have taken it as high as 20MHz (see Commodore 64 attachment SuperCPU for example).
