6502 Introduction
6502 Introduction Philipp Koehn 18 September 2019 some history 1971 First microprocessor on an integrated circuit: Intel 4004 4-bit central processing unit 12 bit address space (4KB) 1975 MOS Technology 6502 |
What is a MOS 6502?
The 6502 was the most prolific variant of the 65xx series family from MOS Technology . The 6501 and 6502 have 40-pin DIP packages; the 6503, 6504, 6505, and 6507 are 28-pin DIP versions, for reduced chip and circuit board cost.
What is a 6500 processor used for?
Another important use of the 6500 family was in video games. The first to make use of the processor design was the 1977 Atari VCS, later renamed the Atari 2600. The VCS used a 6502 variant named the 6507, which had fewer pins, so it could address only 8 KB of memory. Millions of the Atari consoles would be sold, each with a MOS processor.
What is 6502 Org?
6502.org is a resource for people interested in building hardware or writing software for the 6502 microprocessor and its relatives. We continually strive to remain the largest and most complete source for 6502-related information in the world. This includes everything from articles and project descriptions to schematics and source code.
