Mos Technology 6502
built 806 days ago
El MOS Technology 6502 es un microprocesador de 8 bits diseñado por MOS Technology en 1975. Cuando se introduce en el mercado es la CPU completa más barata de lejos, a 1/6 o menos del precio de sus competidoras los gigantes Intel y Motorola. Es además mucho más rápida, y con el Zilog Z80, serán el motor de numerosos desarrollos informáticos que devendrán en la revolución del ordenador doméstico de los 80. El diseño del 6502 es vendido a Rockwell y Synertek (MOS sigue fabricándolo) y licenciado más adelante a numerosas compañías. Todavía se usa en diseños embebidos

Based upon Intel's success with their new microcomputer product line Faggin convinced Vasdasz in 1972 to fund a project to convert the P-MOS 8008 into the newer N-MOS technology. This technology offered about a 2x speedup without making logic changes. After a short study, it was determined that a new mask set was needed because of the incompatibility of transistor size ratios. Faggin reckoned that since a new mask set was needed, he would fix some of the 8008's shortcomings [21].

Vince Briel, aleady well-known in the vintage computing hobby for his Replica 1 and AltairPC systems, will soon sell a new replica -- the Micro-KIM, based on the 8-bit 1975 kit from MOS Technology. MOS itself is famous for its 6502 processor. The new Micro-KIM uses many of the same original parts, has a 23-key keyboard, and is expected to sell starting this summer for $99. The plans will be open-source so anybody can use them, Briel told me tonight.

As mobile technology has become almost a necessity, it is no surprise that personal computing has become a vital learning tool by this time. Educational institutes have commenced a trend of integrating PDAs into their teaching practices (mobile learning). With the capabilities of PDAs, teachers are now able to provide a collaborative learning experience for their students. They are ... preparing their students for possible practical uses of mobile computing upon their graduation.

The C64 used an 8-bit MOS Technology 6510 microprocessor. This was a close derivative of the 6502, with an added 6-bit internal I/O port that in the C64 is used for two purposes: to bank-switch the machine's ROM in and out of the processor's address space, and to operate the datasette tape recorder.
