[Coco] NitrOS9 LEVEL 2 running on Multicomp

Tue Apr 4 15:44:41 EDT 2017

"Official release" (ie in the sourceforge vault) is probably a couple of
months away. I will release an SD-card image snapshot once we have it up
and running successfully on real hardware - maybe a couple of weeks, spare
time permitting
