[Coco] Dual boot OS-9 CF image

[Ken H.]

Thanks!
I can confirm this CF image can be used to boot NitrOS9 on the Tano Dragon
with SuperIDE, using the dual Dragon/Coco EPROMs.
It should also work on a 64K CoCo2.

Your CF image will run on the Dragon as is, but the keyboard is garbled due
to the Dragon's different keyboard wiring. All I had to do to have proper
keyboard input is replace the vtio.dr module with the Dragon's vtio.dr
module and run the mb.ide script.

The problem is that memory is too tight under Level1 with this
configuration. I wasn't  able to run Dynacalc, even after eliminating the
DW modules.
Need to try and further trim the bootlist.
Ken
