context_page_description: The Motorola 6809 is an 8-bit microprocessor CPU with some 16-bit features from Motorola. It was designed by Terry Ritter and Joel Boney and introduced in 1978. It was a major advance over both its predecessor, the Motorola 6800, and the related MOS Technology 6502. Among the systems to use the 6809 are the TRS-80 Color Computer and Dragon 32/64 home computers, the Vectrex game system, and early 1980s arcade machines including Star Wars, Defender, Robotron: 2084, Joust, and Gyruss. Series II of the Fairlight CMI digital audio workstation and Konami's Time Pilot '84 arcade game each use dual 6809 processors.
  Unlike the 6800 and 6502, the 6809 allows fully position-independent code and fully reentrant code in a simple and straightforward way. It was one of the first microprocessors with a hardware multiplication instruction, and it includes full 16-bit arithmetic and a fast interrupt system.
