MOS Technology 6502
The MOS Technology 6502 (typically "sixty-five-oh-two" or "six-five-oh-two") is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. When it was introduced in 1975, the 6502 was, by a considerable margin, the least expensive full-featured microprocessor on the market. It initially sold for less than one-sixth the cost of competing designs from larger companies, such as Motorola and Intel, and caused rapid decreases in pricing across the entire processor market. Along with the Zilog Z80 it sparked a series of projects that resulted in the home computer revolution of the early 1980s.
Popular home video game consoles and computers, such as Atari, Apple II, Nintendo Entertainment System, Commodore 64 and others, used the 6502 or variations of the basic design. Soon after the 6502's introduction, MOS Technology was purchased outright by Commodore International, who continued to sell the microprocessor and licenses to other manufacturers. In the early days of the 6502, it was second-sourced by Rockwell and Synertek, and later licensed to other companies. In its CMOS form, which is produced by the Western Design Center, the 6502 continues to be widely used in embedded applications, with estimated production volumes in the hundreds of millions.

MOS Technology
MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor), also known as CSG (Commodore Semiconductor Group), was a semiconductor design and fabrication company based in Norristown, Pennsylvania, in the United States. It is most famous for its 6502 microprocessor and various designs for Commodore International's range of home computers.
History
MOS Technology, Inc. was originally started in 1969 by Allen-Bradley to provide a second source for electronic calculators and their chips designed by Texas Instruments (TI). In the early 1970s TI decided to release their own line of calculators, instead of selling just the chips inside them, and introduced them at a price that was lower than the price of the chipset alone. Many early chip companies were wiped out in the aftermath; those that survived did so by finding other chips to produce. MOS became a supplier to Atari, producing a custom single-chip Pong system.
Things changed dramatically in 1975. Several of the designers of the Motorola 6800 left Motorola shortly after its release, after management told them to stop working on a low-cost version of the design. At the time there was no such thing as a "design-only" firm (known as a fabless semiconductor company today), so they had to join a chip-building company to produce their new CPU. MOS was a small firm with good credentials in the right area, the east coast of the USA. The team of four design engineers was headed by Chuck Peddle and included Bill Mensch. At MOS they set about building a new CPU that would outperform the 6800 while being similar to it in purpose. The resulting 6501 design was somewhat similar to the 6800, but by using several simplifications in the design, the 6501 would be up to 4 times faster.

MOS Technology SID
The MOS Technology 6581/8580 SID (Sound Interface Device) is the built-in Programmable Sound Generator chip of Commodore's CBM-II, Commodore 64, Commodore 128 and Commodore MAX Machine home computers. It was one of the first sound chips of its kind to be included in a home computer prior to the digital sound revolution.
Together with the VIC-II graphics chip, the SID was instrumental in making the C64 the best-selling computer in history, and is partly credited for initiating the demoscene.
The SID has U.S. Patent 4,677,890, which was filed on February 27, 1983, and issued on July 7, 1987. The patent expired on July 7, 2004.
Design process
The SID was devised by engineer Robert "Bob" Yannes, who later co-founded the Ensoniq digital synthesizer company. Yannes headed a team that included himself, two technicians and a CAD operator, who designed and completed the chip in five months, in the latter half of 1981. Yannes was inspired by previous work in the synthesizer industry and was not impressed by the current state of computer sound chips. Instead, he wanted a high-quality instrument chip, which is the reason why the SID has features like the envelope generator, previously not found in home computer sound chips.

MOS Technology 6507
The 6507 is an 8-bit microprocessor from MOS Technology, Inc.
It is essentially a 6502 chip in a smaller, cheaper 28-pin package. To do this, A15 to A13 and some other signals such as the interrupt lines are not accessible. As a result, it can only address 8 KB of memory, which at the time (1975) was not considered restrictive.
The 6507 and 6502 chips use the same underlying silicon layers, and differ only in the final metallisation layer. This ties the interrupt lines to their inactive level so that they are not vulnerable to generating spurious interrupts from stray noise. The first three digits of the chip identifier are part of the silicon layers, and the final digit is in the metallisation layer. Micro-photography of the 6502 and 6507 shows this difference.
The 6507 was only widely used in two applications, the best-selling Atari 2600 video game console and the Atari 8-bit family floppy disk controllers for the 810 and 1050 drives. In the 2600, the system was further limited by the design of the ROM cartridge slot, which allowed for only 4KB of external memory to be addressed (the other 4KB was reserved for the internal RAM and I/O chip).

3510 transistors in 60 minutes
The MOS 6502 CPU, which was designed in 1975 and powered systems like the Apple II, the Atari 2600, the Nintendo NES and the Commodore 64 for two decades, has always been subject to intense reverse engineering of its inner workings. Only recently, the Visual6502.org project has converted a hi-res die-shot of the 6502 into a polygon model suitable for visually simulating the original mask at the transistor level. This talk will present the way from a chip package to a digital representation, how to simulate transistors in software, and new insights gained form this research about 6502 internals, like "illegal" opcodes.
The presentation only requires a basic understanding of assembly programming and electronics, and is meant to teach, among other things, the methods of efficient and elegant chip design used in the early years of integrated CPUs. The talk consists of three parts. The first part, "6502 from top down", describes the programmer's model, as well as the basic layout of the components of the CPU. In the second part, "6502 from bottom up", we describe how to decap and photograph chips, convert each physical layer of the chip into a polygon model, and how to finally convert this into a network of wires and transistors suitable for logic simulation. The third part, "6502 from the inside out", explains the inner workings of the CPU: how the logic blocks work together, how an instruction is decoded by the PLA ROM into controlling these blocks and busses, and how details like interrupt delivery work. Finally, this information can be used to describe and explain undocumented behaviour, like illegal opcodes and crash instructions, and explain bugs like the BRK/IRQ race, the ROR bug and spurious reads and writes in certain situations.

One of the most influential microprocessors ever designed, the MOS 6502 is credited with ushering in the most rapid democratization of technology in human history: the personal computing revolution.
When it was introduced in 1975 by MOS Technology of Valley Forge, Pennsylvania, the 8-bit microprocessor sold for a fraction of the cost of other microprocessors, causing rapid decreases across the industry. Featured in such seminal products as the Apple I and II, the Commodore PET and the BBC Micro, as well as Atari and Nintendo game consoles, the 6502 microprocessor has been the brains inside toys, office machines, and medical devices too numerous to mention. As one of the most widely used microprocessor architectures of all time, the CMOS related form of the 65XX developed by the Western Design Center is still in production today, with an estimated 6 billion units so far produced.
While the story of Chuck Peddle, the visionary who conceived of the 6502, and that of design team member and founder of the Western Design Center, Bill Mensch, are widely recognized and recorded, the stories of the other MOS Technology engineers and employees who also worked on the 6502 and their contributions are not. Team6502.org seeks to change that.
Through personal accounts or those of family related to the original 6502 design team members including Terry Holdt, Wil Mathys, Rod Orgill, Ray Hirt, Harry Bawcom, Sydney Ann Holt, Walt Eisenhower, and John Paivinen, as well as historical documents including MOS Technology brochures, 6502 schematics, inter-office memos, notes from brainstorming sessions, patent awards, and 6502 testing procedures and results, team6506.org tells the stories of the other MOS Technology engineers and employees behind the chip that put the transformative power of the microprocessor into everybody's hands.
From the moment of its legendary introduction at the Western Electronics Show and Convention (Westcon) more than 40 years ago, where computer enthusiasts from across Silicon Valley, including a young Steve Wozniak, flocked to San Francisco to purchase the 6502, to the legions of computer programmers and historians who continue to debate, discuss, program, and experiment with the iconic chip to this day, the 6502's appeal has spanned time and generations. May team6502.org fan the flame of that enthusiasm by providing new information about the people and processes behind its production, and with it, new food for thought and discussion for those who have carved out a special place in their hearts for the little chip that changed the world.

Through personal accounts or those of family related to the original 6502 design team members including Terry Holdt, Wil Mathys, Rod Orgill, Ray Hirt, Harry Bawcom, Sydney Ann Holt, Walt Eisenhower, and John Paivinen, as well as historical documents including MOS Technology brochures, 6502 schematics, inter-office memos, notes from brainstorming sessions, patent awards, and 6502 testing procedures and results, team6506.org tells the stories of the other MOS Technology engineers and employees behind the chip that put the transformative power of the microprocessor into everybody's hands.
From the moment of its legendary introduction at the Western Electronics Show and Convention (Westcon) more than 40 years ago, where computer enthusiasts from across Silicon Valley, including a young Steve Wozniak, flocked to San Francisco to purchase the 6502, to the legions of computer programmers and historians who continue to debate, discuss, program, and experiment with the iconic chip to this day, the 6502's appeal has spanned time and generations. May team6502.org fan the flame of that enthusiasm by providing new information about the people and processes behind its production, and with it, new food for thought and discussion for those who have carved out a special place in their hearts for the little chip that changed the world.

The MOS Technology 6502 is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. When it was introduced in 1975, the 6502 was, by a considerable margin, the least expensive full-featured microprocessor on the market. It initially sold for less than one-sixth the cost of competing designs from larger companies, such as Motorola and Intel, and caused rapid decreases in pricing across the entire processor market. Along with the Zilog Z80 it sparked a series of projects that resulted in the home computer revolution of the early 1980s.
Popular home video game consoles and computers, such as Atari, Apple II, Nintendo Entertainment System, Commodore 64 and others, used the 6502 or variations of the basic design. Soon after the 6502's introduction, MOS Technology was purchased outright by Commodore International, who continued to sell the microprocessor and licenses to other manufacturers. In the early days of the 6502, it was second-sourced by Rockwell and Synertek, and later licensed to other companies. In its CMOS form, which is produced by the Western Design Center, the 6502 continues to be widely used in embedded applications, with estimated production volumes in the hundreds of millions.

3510 transistors in 60 minutes
The MOS 6502 CPU, which was designed in 1975 and powered systems like the Apple II, the Atari 2600, the Nintendo NES and the Commodore 64 for two decades, has always been subject to intense reverse engineering of its inner workings. Only recently, the Visual6502.org project has converted a hi-res die-shot of the 6502 into a polygon model suitable for visually simulating the original mask at the transistor level. This talk will present the way from a chip package to a digital representation, how to simulate transistors in software, and new insights gained form this research about 6502 internals, like "illegal" opcodes.
The presentation only requires a basic understanding of assembly programming and electronics, and is meant to teach, among other things, the methods of efficient and elegant chip design used in the early years of integrated CPUs. The talk consists of three parts. The first part, "6502 from top down", describes the programmer's model, as well as the basic layout of the components of the CPU. In the second part, "6502 from bottom up", we describe how to decap and photograph chips, convert each physical layer of the chip into a polygon model, and how to finally convert this into a network of wires and transistors suitable for logic simulation. The third part, "6502 from the inside out", explains the inner workings of the CPU: how the logic blocks work together, how an instruction is decoded by the PLA ROM into controlling these blocks and busses, and how details like interrupt delivery work. Finally, this information can be used to describe and explain undocumented behaviour, like illegal opcodes and crash instructions, and explain bugs like the BRK/IRQ race, the ROR bug and spurious reads and writes in certain situations.

One of the most influential microprocessors ever designed, the MOS 6502 is credited with ushering in the most rapid democratization of technology in human history: the personal computing revolution.
When it was introduced in 1975 by MOS Technology of Valley Forge, Pennsylvania, the 8-bit microprocessor sold for a fraction of the cost of other microprocessors, causing rapid decreases across the industry. Featured in such seminal products as the Apple I and II, the Commodore PET and the BBC Micro, as well as Atari and Nintendo game consoles, the 6502 microprocessor has been the brains inside toys, office machines, and medical devices too numerous to mention. As one of the most widely used microprocessor architectures of all time, the CMOS related form of the 65XX developed by the Western Design Center is still in production today, with an estimated 6 billion units so far produced.
While the story of Chuck Peddle, the visionary who conceived of the 6502, and that of design team member and founder of the Western Design Center, Bill Mensch, are widely recognized and recorded, the stories of the other MOS Technology engineers and employees who also worked on the 6502 and their contributions are not. Team6502.org seeks to change that.
Through personal accounts or those of family related to the original 6502 design team members including Terry Holdt, Wil Mathys, Rod Orgill, Ray Hirt, Harry Bawcom, Sydney Ann Holt, Walt Eisenhower, and John Paivinen, as well as historical documents including MOS Technology brochures, 6502 schematics, inter-office memos, notes from brainstorming sessions, patent awards, and 6502 testing procedures and results, team6506.org tells the stories of the other MOS Technology engineers and employees behind the chip that put the transformative power of the microprocessor into everybody's hands.
From the moment of its legendary introduction at the Western Electronics Show and Convention (Westcon) more than 40 years ago, where computer enthusiasts from across Silicon Valley, including a young Steve Wozniak, flocked to San Francisco to purchase the 6502, to the legions of computer programmers and historians who continue to debate, discuss, program, and experiment with the iconic chip to this day, the 6502's appeal has spanned time and generations. May team6502.org fan the flame of that enthusiasm by providing new information about the people and processes behind its production, and with it, new food for thought and discussion for those who have carved out a special place in their hearts for the little chip that changed the world.

The MOS Technology 6502 is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. When it was introduced in 1975, the 6502 was, by a considerable margin, the least expensive full-featured microprocessor on the market. It initially sold for less than one-sixth the cost of competing designs from larger companies, such as Motorola and Intel, and caused rapid decreases in pricing across the entire processor market. Along with the Zilog Z80 it sparked a series of projects that resulted in the home computer revolution of the early 1980s.
Popular home video game consoles and computers, such as Atari, Apple II, Nintendo Entertainment System, Commodore 64 and others, used the 6502 or variations of the basic design. Soon after the 6502's introduction, MOS Technology was purchased outright by Commodore International, who continued to sell the microprocessor and licenses to other manufacturers. In the early days of the 6502, it was second-sourced by Rockwell and Synertek, and later licensed to other companies. In its CMOS form, which is produced by the Western Design Center, the 6502 continues to be widely used in embedded applications, with estimated production volumes in the hundreds of millions.

MOS Technology 6502
The MOS Technology 6502 (typically "sixty-five-oh-two" or "six-five-oh-two") is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology.
