Actually, it may have just become moot.  My 3 has stopped running at
all.  No display, nothing but the click of the relay when you power
it on.  I have moved some of my testing to a 2 but that isn't where
I really want to be so I may be giving up.  I looked on ebay and it
looks like COCO3's don't show up there any more at least not in a
search.

The good news was the SUPERIDE seems to work just fine.  I am DSKINIing
255 virtual disks right now.  I will try putting NitrOS9 on it and see
if it works. But that will require finding a version that actually boots
on a 2 from Drivewire and I have not found one in any of the stuff that
is currently available.

If things continue in the direction they seem to be going I may be
looking to dump all that I have.  :-(
