The Motorola 6809 was originally produced in 1 MHz, 1.5 MHz (68A09) and 2 MHz (68B09) speed ratings. Faster versions were produced later by Hitachi. With little to improve, the 6809 marks the end of the evolution of Motorola's 8-bit processors; Motorola intended that future 8-bit products would be based on an 8-bit data bus version of the 68000 ...
The original version was distributed on 8-inch floppy disks; the (smaller) version for 5.25-inch floppies is called mini-Flex.It was also later ported to the Motorola 6809; that version is called Flex09. [2]

UniFLEX is a Unix-like operating system developed by Technical Systems Consultants (TSC) for the Motorola 6809 family which allowed multitasking and multiprocessing.. It was released for DMA-capable 8" floppy, extended memory addressing hardware (software controlled 4KiB paging of up to 768 KiB RAM [1]), Motorola 6809 based computers.
The 6309 is fabricated in CMOS technology, while the 6809 is an NMOS device. As a result, the 6309 requires less power to operate than the 6809. Although it is a dynamic design (the datasheet [3] specifies a 500 kHz minimum clocking frequency and it will lose its state when the clock speed is too low), it can be paused for up to 15 cycles.

The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel 's x86 microprocessors.
