 MOS Technology 6510 - Wikipedia, the free encyclopedia
The MOS Technology 6510 is a microprocessor designed by MOS Technology, Inc., and is a direct successor of the very successful 6502.
The primary changes from the 6502 were the addition of clock pins, which allowed the chip to make use of external clocks, and the addition of six general purpose I/O pins.
In both the C64 and SX-64 the extra pins of the processor were used for bank switching, and in the C64 also for controlling the electric motor of the Datassette tape recorder.

Note that MOS Technologies Incorporated is wholly unrelated to MOSTek which was a 1984 Texas Instruments spin off.
MOS was able to produce the chips at this low price because they increased their yield dramatically by reducing flaws in their chips 'masks' before starting production.
The integrated circuit chip that went into CBM's successful SR36/37 calculator came from MOS Technology, as does the current chip for the SR7919D calculator (a model which is rumored to have around 25 per cent of the UK scientific calculator market) and others of the current CBM range.

 MOS Technologies : Encyclopedia at AudioXchange - Online Store & Product Reviews
MOS Technologies, also known as Commodore Semiconductor Group, was a microprocessor and calculator company famous for its 6502 processor.
When it was introduced it was the least expensive full featured CPU on the market by far, about 1/6th the price, or less, of competing designs from larger companies such as Motorola and Intel.
Motorola immediately sued, although today the case would have been dismissed out of hand, and the damage to MOS was enough for them to agree to stop producing the 6501.

The resulting 6501 design was somewhat similar to the 6800, but by using several simplifications in the design, the 6501 would be much faster, up to four times.
After Commodore's bankruptcy in 1994, Commodore Semiconductor Group (the formerly MOS Technology, Inc.) was bought by its former management for about $4.3 million, plus an additional $1 million to cover miscellaneous expenses including EPA liens.

MOS originally started up to provide a second source for TexasInstruments designed electronic calculators and the chips inside them.
MOS also released a series ofsimilar CPUs using external clocks, which added a "1" to the name in the 3rd digit, as the 6512 through 6515.
MOS had also designed a simple computer kit called the KIM-1, primarily to "show off"the 6502 chip.

The notion of appropriate technology, however, was developed in the twentieth century to describe situations where it was not desirable to use very new technologies or those that required access to some centralized infrastructure or parts or skills imported from elsewhere.
Intermediate technology, more of an economics concern, refers to compromises between central and expensive technologies of developed nations and those which developing nations find most effective to deploy given an excess of labour, and scarcity of cash.
Persuasion technology, in economics, definitions or assumptions of progress or growth are often related to one or more assumptions about technology's economic influence.

As the calculator market grew MOS eventually became largely beholden to Commodore_International (then Commodore Business Machines), who bought practically all of their supply for their line of calculators.Things changed dramatically in 1975.
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 any of their designs.
Far and away the most popular of these was the 6507, which was used in the Atari_2600 and in Atari disk drives.

The 6507 was only widely used in two applications, the bestselling Atari2600 video game console and the Atari 8-bit floppydisk controllers for the 810 and 1050 drives.
By the time the 6502 line was becoming widely used around 1980, ROM and RAM semiconductor memory prices had fallen to the point where the 6507 was no longera worthwhile simplification.

Some of the designers (notably Chuck Peddle) left to start MOS Technologies (later bought by Commodore), which introduced the 650x series which included the 6501 (pin compatible with the 6800, taken off the market almost immediately for legal reasons) and the 6502 (used in early Commodores, Apples and Ataris).
The 650x was little endian (lower address byte could be added to an index register while higher byte was fetched) and had a completely different instruction set from the big endian 6800.
The roots of the PIC originated at Harvard university (see Harvard Architecture) for a Defense Department project, but was beaten by a simpler (and more reliable at the time) single memory design from Princeton.

Since then they have moved much of the original MOS catalog to CMOS, and the 6502 continues to be a popular CPU for medical equipment and car dashboard controllers.

The MOS Technology 8563 aka VDC (for Video Display Controller) was MOS' 80-column RGB display video chip used in the Commodore 128 home computer (the C128 also had a VIC-II for producing bitmap graphics and 40-column text, and for C64 compatibility).
The 8563 was a departure from other MOS video chip designs in that it had its own dedicated memory, and memory space, separate from system memory.
In addition, yields on the chip were very low, and Commodore's official position after the release of the C128 was that the VDC was incapable of producing bitmapped graphics.

The 6503 to 6507 are cut-down versions of the same chip, with only 28 pins.
Internally, the chips are the same: the programmer will use exactly the same instructions regardless of which chip is involved.

This technology used a standard television CRT that utilized a video controller to scan the image from top to bottom, turning on or off the individual addressable points on the screen, and providing information as to the color of the points.
This technology has been expanded from simple subroutine calls to include features that provide for interoperability and system modifiability in support of the requirement for data sharing between multiple applications.
The next technology to hit the market was dedicated (nonprogrammable) video game consoles, which were often inaccurately called "analog" but actually used discrete logic.
