Along with the Zilog Z8. Popular home video game consoles and computers, such as the Atari 2. Atari 8 bit family, Apple II, Nintendo Entertainment System, Commodore 6. Soon after the 6. 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 6. Rockwell and Synertek, and later licensed to other companies. My Account Shop. ezgo. Easily track orders, view your purchase history and manage your vehicles by establishing an account with Shop. In its CMOS form, which was developed by the Western Design Center, the 6. History and useeditOrigins at Motorolaedit. Motorola 6. 80. 0 demonstration board built by Chuck Peddle and John Buchanan in 1. The 6. 50. 2 was designed by many of the same engineers that had designed the Motorola 6. Motorola started the 6. Tom Bennett as the main architect. The chip layout began in late 1. February 1. 97. 4 and the full family was officially released in November 1. John Buchanan was the designer of the 6.

Rod Orgill, who later did the 6. Buchanan with circuit analyses and chip layout. Bill Mensch joined Motorola in June 1. University of Arizona at age 2. His first assignment was helping define the peripheral ICs for the 6. Peripheral Interface Adapter PIA. Motorolas engineers could run analog and digital simulations on an IBM 3. Bennett hired Chuck Peddle in 1. He contributed in many areas, including the design of the 6. ACIA serial interface. Motorolas target customers were established electronics companies such as Hewlett Packard, Tektronix, TRW and Chrysler. In May 1. 97. 2, Motorolas engineers began visiting select customers and sharing the details of their proposed 8 bit microprocessor system with ROM, RAM, parallel and serial interfaces. In early 1. 97. 4, they provided engineering samples of the chips so that customers could prototype their designs. Motorolas total product family strategy did not focus on the price of the microprocessor, but on reducing the customers total design cost. They offered development software on a timeshare computer, the EXORciser system debugging system, onsite training and field application engineer support. Both Intel and Motorola had initially announced a 3. The IBM System3. The actual price for production quantities was much less. Motorola offered a design kit containing the 6. Peddle, who would accompany the sales people on customer visits, found that customers were put off by the high cost of the microprocessor chips. To lower the price, the IC chip size would have to shrink so that more chips could be produced on each silicon wafer. This could be done by removing inessential features in the 6. MOS transistors. Peddle and other team members started outlining the design of an improved feature, reduced size microprocessor. At that time, Motorolas new semiconductor fabrication facility in Austin, Texas was having difficulty producing MOS chips and mid 1. Also, many of the Mesa, Arizona employees were displeased with the upcoming relocation to Austin. Motorola Semiconductor Products Divisions management was overwhelmed with problems and showed no interest in Peddles low cost microprocessor proposal. Chuck Peddle was frustrated with Motorolas management for missing this new opportunity. In a November 1. 97. Motorolas Chairman, Robert Galvin, agreed. He said, We did not choose the right leaders in the Semiconductor Products division. The division was reorganized and the management replaced. New group vice president John Welty said, The semiconductor sales organization lost its sensitivity to customer needs and couldnt make speedy decisions. Peddle began looking for a source of funding for this new project and found a small semiconductor company in Pennsylvania. In August 1. 97. 4, Chuck Peddle, Bill Mensch, Rod Orgill, Harry Bawcum, Ray Hirt, Terry Holdt and Wil Mathys left Motorola to join MOS Technology. Mike James joined later. Of the seventeen chip designers and layout people on the 6. There were 3. 0 to 4. That December, Gary Daniels transferred into the 6. Tom Bennett did not want to leave the Phoenix area so Daniels took over the microprocessor development in Austin. His first project was a depletion mode version of the 6. The faster parts were available in July 1. This was followed by the 6. RAM and an on chip clock oscillator circuit. Moving to MOS Technologyedit. A 1. 97. 3 MOS Technology advertisement highlighting their custom integrated circuit capabilities. MOS Technology was formed in 1. General Instrument, Mort Jaffe, Don Mc. Laughlin, and John Pavinen, to produce metal oxide semiconductor MOS integrated circuits. Allen Bradley, a supplier of electronic components and industrial controls, acquired a majority interest in 1. The company designed and fabricated custom ICs for customers and had developed a line of calculator chips. On August 1. 9, 1. Motorola employees moved into MOS Technologys headquarters at Valley Forge, Pennsylvania. The goal was to design and produce a low cost microprocessor for embedded applications and to target as wide as possible a customer base. This would be possible only if the microprocessor was low costand in the semiconductor business, chip size determined cost. The size goal required n channel depletion mode MOS transistors, a more advanced process than MOS Technologys calculator chips used. John Pavinen was able to have the fabrication process ready by June 1. Chuck Peddle, Rod Orgill, and Wil Mathys designed the initial architecture of the new processors. There would be two microprocessors the 6. Motorola 6. 80. 0, while the 6. These processors would not run 6. A September 1. 97. EDN magazine gives this summary of the design The MOS Technology 6. X family represents a conscious attempt of eight former Motorola employees who worked on the development of the 6. With the benefit of hindsight gained on the 6. MOS Technology team headed by Chuck Peddle, made the following architectural changes in the Motorola CPU3. The second B accumulator was omitted. The 1. 6 bit 6. 80. Three state control was eliminated from the address bus outputs. A clock generator was included on the chip. The address bus was always active so the VMA valid memory address output was eliminated. An 8. 08. 0 type RDY signal for single cycle stepping was added. The chip high level design had to be turned into drawings of transistors and interconnects. At MOS Technology, the layout was a very manual process done with color pencils and vellum paper. The layout consisted of thousands of polygon shapes on six different drawings one for each layer of the semiconductor fabrication process. Rod Orgill was responsible for the 6. John Buchanan at Motorola on the 6. Bill Mensch did the 6. Peripheral Interface Adapter PIA at Motorola. Harry Bawcom, Mike James and Sydney Anne Holt helped with the layout. The size goal for the 6. At that time the technical literature would state the length and width of each chip in mils 0. A smaller chip area means more chips per silicon wafer and greater yield as defects are generally randomly but uniformly scattered across the wafer area. So the more chips per wafer, the smaller the ratio of defective chips to total wafer chips. The original 6. 80. The first 6. 50. 2 chips were 1. E Z GO Login or Create Account.
