	Motorola 6809
		The 6809 was a major advance over both its predecessor, the Motorola 6800 and also over the MOS Technologies 6502.
		The 6809 was source compatible[?] with the 6800, even though the 6800 had 78 instructions and the 6809 only had 59.
		The optimisation of the 6809 processor meant that, unlike many processors of the day, the instructions were mostly hardwired into the processor, rather than written using microcode.

	Motorola 6809 - Wikipedia, the free encyclopedia
		Among the significant enhancements introduced in the 6809 were the use of two 8-bit accumulators (A and B, which could be combined into a single 16-bit register, D), two 16-bit index registers (X, Y) and two 16-bit stack pointers (U, S).
		The 6809 was source-compatible with the 6800, though the 6800 had seventy-eight instructions to the 6809's fifty-nine.
		The Hitachi 6309 was an enhanced version of the 6809 with extra registers and additional instructions, including block move, additional multiply instructions and hardware-implemented division.

	OS-9
		The first version ("level one") was written in assembly language for the Motorola 6809 processor, and provides a single 64K address space in which all processes ran; a later 6809 version ("level two") takes advantage of memory mapping hardware.
		Later, OS-9/6809 was converted to Motorola 68000 assembly language and extended, and a still further extended version was written mostly in C for portability.
		OS-9 has had a modular design from the beginning, influenced by the notions of how the designers of the 6809 thought software would be sold in the future as described in a three-part series of articles in Jan-Mar 1979 Byte magazine.

		I had taken on some work with a local company who was using the "new" Motorola 6809 processor.
		The 6809 was a vastly different architecture, and had many features which were ahead if its time (such as stack relative addressing).
		In fact, the 6809 still holds the reputation as one of the most powerful general purpose 8-bit processors ever produced.

		No progress on the 6809 code today, because I've been distracted by looking at the original 6502 code on the UK101.

	6809 Project
		OK a fix for me but not a fix for all sorts of 6809, so I trashed that code and optimised it from square one until it would run on a standard 6809 -which it does - fortunately with time in hand.
		The first 6809 keyboard interface is of course to the right.
		What I’ve done here is taken the serial output from 6809 project (1), and fed it into the serial input (the 25 way D type) of the 8085 board.

	Motorola 6809 - Wikipedia, la enciclopedia libre
		El 6809 fue un avance mayor sobre sus dos predecesores, el Motorola 6800 y el MOS Technology 6502.
		Entre las mejoras más significativas que el 6809 introdujo sobre sus predecesores fue el empleo de dos acumuladores de 8 bits, mejor que uno en el 6502, el cual puede ser combinado en un único registro de 16 bits.
		La optimización del procesador 6809 significó que, a diferencia de muchos procesadores de aquel entonces, las instrucciones fueron en su mayoría construidas dentro del procesador, en lugar de ser escritas utilizando microcódigo o microprogramación.

		In addition to the system stack pointer the 6809 includes additional user stack pointer.
		Indexed addressing of the 6809 was expanded to provide new addressing modes: indexed addressing using one of 4 registers (2 stack points, X index register or new Y index register) with 5-bit, 8-bit or 16-bit offset, indexed with accumulator offset, indexed with auto-increment or auto-decrement by 1 or 2, and relative to program counter addressing.
		The Motorola 6809 was produced in two versions - with on-chip clock (6809) and with external clock input (6809E).
