[Coco] SuperIDE on my 6809 computer

[Aaron Wolfe]

I'm not sure if a superIDE would be the most direct route to some
flash based storage or not... I suppose if you wanted to have a coco
cart compatible interface anyway it might be a good way to do it.  if
you don't care about having a coco compatible cart slot, seems like a
lot of work.
you could look at designs that instead use a serial port to speak high
level commands to a cheap 'one piece' SD or CF type
controller/interface, which would be much simpler from a hardware
point of view.

although os9 ran on swtpc and gimix etc, nitros9 does not support the
swtpc specifically that I know of.  it supports the coco, several
models of dragon, and atari's with the liber09 upgrade.  it is
possible to boot nitros9 without the coco *graphics* specific bits
(headless over a serial port or drivewire channel)  but I'm not sure
how many other parts of hardware that a coco/dragon has are required
by default.  i'm sure you could use it but i'm not sure how much work
it might be.

the 'stock' serial drivers for nitros9 support the 6551 and the
bitbanger.  there is a module called s16550 in the 3rd party area of
the repository but i'm not sure what state it's in.  nothing for 6850s
that I've seen in there.  its not too hard to make a serial driver for
nos9 though.  thats one bit of nitros9 that is actually pretty well
documented.
