[Coco] origins of OS-9

I just found a Microware ad in the Mar-Apr 1979 issue of 68 Micro
Journal (vol1 no2).
Products (all for 6800) include a Lisp interpreter, the A/BASIC
compiler and interpreter, an Eliza chat program, a chess game, and
most interestingly RT/68.
RT/68 is described as:
RT/68 Real Time Operating System
MikBUG compatible ROM that combines an improved monitor/debugger with
a powerful multitasking operating system. Supports up to 16
concurrent tasks at 8 priority levels plus real time clock and
interrupt control. Thousands in use since 1976 handling all types of
applications. Available on 6830 (MIKBUG-type) or 2708 (EPROM-type)
ROM. Manual is a classic on 6800 real-time applications and contains
a full source program listing. $55
..so it seems Microware had quite some experience with operating
systems and BASICs prior to the 6809. Motorola's decision to partner
with them for the Basic09 and OS-9 projects may well have been based
on these products, and I do wonder if some of the ideas if not the
code of RT/68 are present in OS-9.
