[Coco] CoCo TALK #18 an introduction to OS9

[L. Curtis Boyle]

That was Frank Hogg’s vision with the TC-9/TC-70 (6809 with it’s 1 MB of RAM, and 68070 as the main controller). He also had 68020 and 68030 boards that could do the same thing. But, aside from test programs, I don’t think the software to drive all of this under OSK/OS9 was ever completed.
