Trade ChipMOS TECHNOLOGIES
MOS Technology, Inc. ("MOS" being short for semiconductor oxide metal), later known as CSG (Commodore Semiconductor Group), was a semiconductor design and manufacturing company based in Noriston, Pennsylvania, in the United States. Among the most famous processors are 6502 and various designs for the International Commodore collection of home computers. MOS Technology, Inc. originally started in 1969 by Alan Bradley to provide a second source of computers and chips designed by Texas Instruments (TI). In the early 1970s TI decided to release their own line of calculators, instead of selling chips just inside them, and offering them at a lower price than the chip set alone. Many early chip companies relied on chip sales and were subsequently eliminated; MOS has become a supplier of Atari, and produces a dedicated single-slide pong system. things changed dramatically in 1975. Many Motorola 6800 designers left Motorola shortly after its release, after the administration told them to stop working on a low-cost version of the design. At the time there was no such thing as a pure-operated semiconductor foundry, so they had to join a company to build chips to produce a new CPU. MOS was a small company with good credentials in the right area, the east coast of the United States of America. Chuck Blair led the team of four design engineers and was joined by Bill Mensch. In MOS they put around building a new CPU That would outperform the 6800 while being so similar in purpose and much less expensive. The resulting 6501 design was fairly similar to the 6800, but using several design simplifications, the 6501 would be up to 4 times faster.
