KIM-1
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. History MOS Technology's first processor, the 6501, could be plugged into existing motherboards that used the Motorola 6800, allowing potential users (i.e. engineers and hobbyists) to get a development system up and running very easily using existing hardware. Motorola immediately sued, forcing MOS to pull the 6501 from the market. Changing the pin layout produced the "lawsuit-friendly" 6502. Otherwise identical to the 6501, it nevertheless had the disadvantage of having no machine in which new users could quickly start playing with the CPU. Chuck Peddle, leader of the 650x group at MOS (and former member of Motorola's 6800 team), designed the KIM-1 in order to fill this need. ...

MOS Technology 6501
The MOS Technology 6502 (typically pronounced "sixty-five-oh-two" or "six-five-oh-two") William Mensch and the moderator both pronounce the 6502 microprocessor as ''"sixty-five-oh-two"''. is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of that design. When it was introduced in 1975, the 6502 was the least expensive microprocessor on the market by a considerable margin. It initially sold for less than one-sixth the cost of competing designs from larger companies, such as the 6800 or Intel 8080. Its introduction 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 video game consoles and home computers of the 1980s and early 1990s, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microchess
''Microchess'', by Peter R Jennings, Peter R. Jennings, was the first commercially successful chess program for microcomputers. Originally designed for the MOS Technology KIM-1 it was released on December 18, 1976. ''Microchess'', as small as it was in terms of program size, could still play passable chess on the KIM-1 with its MOS Technology 6502, 6502 microprocessor, 1 kilobyte of memory, simple hex keyboard, and seven-segment display. Selling it at a price of US$10, Jennings refused to sell the rights of the program to Chuck Peddle (president of MOS Technology) for $1000. It was the first software package to sell 50,000 copies. Jennings founded Personal Software to publish ''Microchess'' to the nascent microcomputer market. Money made from ''Microchess'' and other software projects allowed Jennings, together with Dan Fylstra, to launch VisiCorp company, and underwrite the development of VisiCalc, the first spreadsheet. ''Microchess'' was later expanded into a more fully fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIM-65
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. Available software included a line-oriented machine code monitor, BASIC interpreter, assembler, Pascal, PL/65, and FORTH development system.

Chuck Peddle
Charles Ingerham Peddle (November 25, 1937 – December 15, 2019) was an American electrical engineer best known as the main designer of the MOS Technology 6502 microprocessor, the single-board computer, and its successor, the Commodore PET personal computer, both based on the 6502. Biography Peddle was born in Bangor, Maine, United States on November 25, 1937. He worked in a radio station while in high school. In 1955, Peddle joined the United States Marine Corps. He attended the University of Maine where he earned a Bachelor of Science (B.Sc.) degree in engineering physics. Afterward, he went to work for General Electric working with time-sharing systems. In 1973, Peddle worked at Motorola on developing the 6800 processor. Peddle recognized a market for a very low price microprocessor and began to champion such a design to complement the $300 Motorola 6800. His efforts were frustrated by Motorola management and he was told to drop the project. He then left for MOS Techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOS Technology
MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor), later known as CSG (Commodore Semiconductor Group) and GMT Microelectronics, was a semiconductor design and fabrication company based in Audubon, Pennsylvania. It is most famous for its 6502 microprocessor and various designs for Commodore International's range of home computers. History Three former General Instrument executives, John Paivinen, Mort Jaffe and Don McLaughlin, formed MOS Technology in Valley Forge, Pennsylvania in 1969. The Allen-Bradley Company was looking to provide a second source for electronic calculators and their chips designed by Texas Instruments (TI). In 1970 Allen-Bradley acquired a majority interest in MOS Technology. 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 reliant on sales of cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-board Computer
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computers or portable computers integrate all their functions onto a single printed circuit board. Unlike a desktop personal computer, single board computers often do not rely on expansion slots for peripheral functions or expansion. Single board computers have been built using a wide range of microprocessors. Simple designs, such as those built by computer hobbyists, often use static RAM and low-cost 32- or 64-bit processors like ARM. Other types, such as blade servers, would perform similar to a server computer, only in a more compact format. A computer-on-module is a type of single-board computer made to plug into a ca ...

Synertek
Synertek, Inc. was an American semiconductor manufacturer founded in 1973. The initial staff consisted of Bob Schreiner (the CEO), Dan Floyd, Jack Balletto, and Gunnar Wetlesen and Zvi Grinfas. Schreiner, Floyd, Balletto and Wetlesen were all formerly of Fairchild Semiconductor, and Synertek is thus one of the many "Fairchildren". The company became a major vendor during the late 1970s and early 1980s on the strength of their licensed production of the MOS 6502, one of the most successful microprocessors of the era. Synertek won supply deals with Apple Computer and Atari, who would produce millions of home computer and games consoles with Synertek 6502's inside. Synertek's original production factories had been cobbled together with used equipment, and quickly ran out of capacity for ever-growing orders. The board of directors was unwilling to fund the construction of a new factory that could handle the demand. This led to a 1979 deal with Honeywell, who agreed to buy the company ...

ASCII
ASCII ( ), abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Because of technical limitations of computer systems at the time it was invented, ASCII has just 128 code points, of which only 95 are , which severely limited its scope. All modern computer systems instead use Unicode, which has millions of code points, but the first 128 of these are the same as the ASCII set. The Internet Assigned Numbers Authority (IANA) prefers the name US-ASCII for this character encoding. ASCII is one of the List of IEEE milestones, IEEE milestones. Overview ASCII was developed from telegraph code. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Work on the ASCII standard began in May 1961, with the first meeting of the American Standards Association's (ASA) (now the American Nat ...
