Have you tried doing it yet? I have a 40 track 5.25 drive and I can read
and write 35 track diskettes just fine. The determining factor is what
DECB or OS-9 is currently configured as.

I have installed 4 or 5 512K upgrades, and it is simply. You remove the
existing 4 memory chips, clip out two capacitors, I think C64 and C65,
then plug in the upgrade. Be sure to keep your body's static potential 
equal to the CoCo's! (Use a static strap or always keep part of your
body in contact with a ground point onthe motherboard.)
The chips in the upgrade are standard DRAMS, 4464's I think, or some
number very close! <grin>

>3. Is there anyway to hook up the RGB output of the Coco to a Tandy CM-11?
I don't think that is possible, but someone else may be able to offer
more information.
