Not I.  I have simply used a CoCo for what little I've done.

> It would be nice to run OS9 on these things,
The CoCo ROM can be replaced with a OS-9 boot ROM.  Cloud-9 sells the
software kits.  You will have to acquire the hardware and do the
interfacing.  So far the CoCo 1, early American CoCo 2 and first Korean CoCo
2 with 2 8k ROMs are not "really" supported.  (The CoCo 2"A" and "B" models
use a 27128 compatible ROM.)

That makes sense to me.

Cost and time wise? I'm inclined to suggest the Micro-Stamp/PIC line of
equipment as a cheaper and better supported line.
