Series II of the Fairlight CMI digital audio workstation and Konami's Time Pilot '84 arcade game each use dual 6809 processors. Hitachi was a major user of the 6809 and later produced a further updated version as the Hitachi 6309. ==History== ===6800 and 6502=== The Motorola 6800 was designed beginning in 1971 and released in 1974.

Peddle and a number of other members of the 6800 team left Motorola for MOS Technology and introduced this design in 1975 as the MOS Technology 6502.
For those where price was not the primary concern, but outright performance was, the new designs outperformed it by as much as an order of magnitude. Even before the 6809 was released, in 1976 Motorola had launched its own advanced CPU project, then known as Motorola Advanced Computer System on Silicon project, or MACSS.
It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978.
This process led Intel to begin the design of a series of 16-bit processors, which emerged as the Intel 8086 in 1978.
Among these was the Intel 8086, released the same year, and its lower-cost version, the Intel 8088 of 1979.
Although too late to be chosen for the IBM PC project, when MACSS appeared as the Motorola 68000 in 1979 it took any remaining interest in the 6809.
It was not feature competitive with newer designs and not price competitive with older ones, and saw relatively little use in the market as a result. It found use in the TRS-80 Color Computer, Dragon 32/64, and Thomson MO/TO home computers, the Vectrex game system, and early 1980s arcade machines including Star Wars, Defender, 2084, Joust, and Gyruss.
Tandy (Radio Shack) was brought in as a retail partner and sold them under the name "VideoTex", but the project was ultimately canceled shortly after its introduction in 1980.
It was used in traffic signal controllers made in the 1980s by several different manufacturers, as well as Motorola's SMARTNET and SMARTZONE Trunked Central Controllers (so dubbed the "6809 Controller").
The introduction of the Micralign to Motorola's lines allowed further reductions and by 1981 the price of the then-current 6800P was slightly less than the equivalent 6502, at least in single-unit quantities.
Such was the case in practice; in 1981 the 6809 sold in single-unit quantities for roughly six times the price of a 6502.
A feeling for the problem can be seen in the Byte Sieve assembly language results against other common designs from the era (taken from 1981 and 1983): Although the 6809 did offer a performance improvement over the likes of the 6502 and Z80, the improvement was not in line with the increase in price.
