Thanks, Bob.  I really should search Google, but I get never seem ask 
the right questions and get frustrated  wading through the crap.  I've 
been going through a similar situation as a Mac owner who installed 
Virtual PC with Windows 2000 Pro.  For me, trying to learn the new 
system is like learning a new language.  A pox on both Steve's and 
Bill's houses.

As I mentioned in my original request, I already have the Grizzly CoCo 
for nearly 10 years.  It began as a  3 3.5" FD with remote CoCo keyboard 
with a 65W PS slightly smaller than the one I saw in Jameco.  Kept 
adding everything but the kitchen sink until I got to the ZIP drive. 
 The PS just did not have enough poop for an internal ZIP.  The 150W 
supply in Jameco is about 1.5" longer, but there is plenty of space 
along that side for it and the bunching up of its cables.

I am interested in how you did the portable ... especially the display. 
 Can you expand on it?
