A Squeak 2.8 image, circa about 2000, is still usable, but Squeak 1.1
from 1997 is not.

Older images have all of what is now called "VMMaker" in the base
image, so it's a good idea to keep a couple of these older images
at hand (ftp.squeak.org). Going back to Squeak 3.4 (a good solid
version) is usually far enough back to answer questions like this.
