The architecture also inspired the MOS Technology 6502, and that company initially started in the microprocessor business producing 6800 replacements.

For example, the MOS Technology 6502 has only one general purpose register (the accumulator).

Primary among these were the lack of a reliable local source of the MOS Technology 6502 microprocessor.

It was a major advance over both its predecessor, the Motorola 6800, and the related MOS Technology 6502.

The 6507 is an 8-bit microprocessor from MOS Technology, Inc.

The Atom was a progression of the MOS Technology 6502 based machines that the company had been making from 1979.

The 6581 was replaced with the MOS Technology 8580 in 1987.

MOS Technology 6502 (1975 similar to 6800, but incompatible)

Not to be confused with MOS Technology or Mustek Systems.

This was easy since MOS Technology had both its research and development lab and semiconductor plant at the same location.
