The Mitsubishi 740 family has a processor core that executes a superset of the 6502 instruction set including many of the extensions added in the 65C02. There is a core set of new instructions common across all 740 family members, plus other instructions that exist in specific parts.

The most significant byte (MSB) of the aborted instruction's address is pushed onto the stack. The least significant byte (LSB) of the aborted instruction's address is pushed onto the stack. The status register is pushed onto the stack. The interrupt disable flag is set in the status register. PB is loaded with $00.
February 2025) (Learn how and when to remove this message) The RISC-V instruction set refers to the set of instructions that RISC-V compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.
This is set to zero on startup or reset, meaning that its store-Z-to-memory instruction, STZ, works just like it does in the 65C02 where the same instruction means store-zero-to-memory. This allows unmodified 65C02 code to run on the 65CE02. A number of other instructions are added or modified to allow access to the Z register.

It is based on the 8/16-bit WDC 65C816, which was developed between 1982 and 1984 for the Apple IIGS personal computer. It has 92 instructions, an 8-bit data bus, a 16-bit accumulator, and a 24-bit address bus. The CPU runs between 1.79 MHz and 3.58 MHz, and uses an extended MOS Technology 6502 instruction set.
The Mensch Computer is a personal computer system produced by the Western Design Center (WDC). It is based on the WDC 65C265 microcontroller, which implements the instruction sets of two microprocessors: the 16-bit W65C816/65816, and the 8-bit 6502. [1] The computer is named after Bill Mensch, designer of the 6502 and subsequent series of ...
