The KIM-1, short for Keyboard Input Monitor, is a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976. It was very successful in that period, due to its low price (thanks to the inexpensive 6502 microprocessor) and easy-access expandability.
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.

The 6502 programming manual thus requires each ISR to reset or set the D flag if it uses the ADC or SBC instruction, but occasionally a human programmer may mistakenly omit to do this, causing a bug. For example, the Commodore 64 's KERNAL did not correctly handle this processor characteristic, requiring that IRQs be disabled or re-vectored ...
Their moves legitimized the 6502, and by the show's end, the wooden barrel full of samples was empty. [citation needed] The 6502 would quickly go on to be one of the most popular chips of its day. A number of companies licensed the 650x line from MOS, including Rockwell International, GTE, Synertek, and Western Design Center (WDC).
The Commodore PET is a line of personal computers produced starting in 1977 by Commodore International. [3] A single all-in-one case combines a MOS Technology 6502 microprocessor, Commodore BASIC in read-only memory, keyboard, monochrome monitor, and, in early models, a cassette deck.
It is a modified form of the very successful 6502. The 6510 is widely used in the Commodore 64 (C64) home computer and its variants. It is also used in the Seagate ST-251 MFM harddisk. [1] The primary change from the 6502 is the addition of an 8-bit general purpose I/O port
GeckOS is a multitasking operating system for MOS 6502, and compatible processors such as the MOS 6510. [1] The GeckOS operating system is one of the few successful attempts to implement a Unix-like operating system on the 6502 architecture.
The CSG 65CE02 is an 8/16-bit microprocessor developed by Commodore Semiconductor Group in 1988. [1] It is a member of the MOS Technology 6502 family, developed from the CMOS WDC 65C02 released by the Western Design Center in 1983.
