At 1 MHz, the most popular speed for the original 6502, the 65C02 requires only 20 mW, while the original uses 450 mW, a reduction of over twenty times. [4] The manually optimized core and low power use is intended to make the 65C02 well suited for low power system-on-chip (SoC) designs.
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.
6502 A 1 MHz chip used in KIM-1 and other single board computers in the mid-1970s. 6502A A 1.5 MHz chip used in Asteroids Deluxe and at 2 MHz in the BBC Micro: 6502B Version of the 6502 capable of running at a maximum speed of 3 MHz instead of 2 MHz. The B was used in both the Apple III and early Atari 8-bit computers, each running at ~1.8 MHz. [c]
The 65xx family of microprocessors, consisting of the MOS Technology 6502 and its derivatives, the WDC 65C02, WDC 65C802 and WDC 65C816, and CSG 65CE02, all handle interrupts in a similar fashion. There are three hardware interrupt signals common to all 65xx processors and one software interrupt , the BRK instruction.
KIM-1 computer in operation 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.
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).
AIM-65 Comelta Drac-1 Comelta Drac-1 and expansion box Back of expansion box. The Rockwell AIM-65 computer is a development computer introduced in 1978 based on the MOS Technology 6502 microprocessor. The AIM-65 is essentially an expanded KIM-1 computer.
The BASIC included on the original PET 2001 was known as Commodore BASIC 1.0; Microsoft supplied Commodore with a source listing for their 6502 BASIC, essentially a port of BASIC-80, and Commodore performed the rest of the work themselves, including changing the startup screen and prompts, adding I/O support, the SYS command for invoking ...
