David,

You make a solid point about sticking with the version of 
Squeak the image was made for.  So for the purpose of the 
class, I may well do so.  Installing and running different 
versions of Squeak might be a lesson in itself.

However, did I understand correctly that you were able to 
use the Ready.image with Squeak v5-ish?  If so, that means 
I'm doing something wrong, so would love to get educated 
on that issue.
