MOS Technologies
A {microprocessor} design company started by some
(ex-{Motorola}?) designers, shortly after the {Intel 8080} and
{Motorola 6800} appeared, in about 1975. MOS Technologies
introduced the {650x} series, based on the {Motorola 6800}
design, though they were not exact clones for legal reasons.
By the time the 6510 was used in the {Commodore 64}, around
September 1981, MOS were a wholly owned subsiduary of
Commodore(?).
