Are these still available somewhere? under what name?
Hi David,
earlier Squeak versions are available at
http://ftp.squeak.org/
The projects you are looking for are e.g. in 3.6. This image still runs fine in a current 4.x VM (but not Cog). You can choose "save project as file" from the world menu. The resulting .pr file still works fine in e.g. the current Etoys release from
http://squeakland.org/
A project does not contain the classes, just the objects on screen. As mentioned previously, these demos were made by constructing objects interactively, not code. If the image does not have the classes, you cannot load them. The Etoys line of images was developed with backwards-compatibility in mind, it still has all the necessary code, that's why it works.
I'm pretty sure it would be reasonably simple to make it work in current Squeak too. E.g. when trying to load the project, it is missing the WatchMorph class. If you asked on the Squeak developers list, someone surely would know where we put those classes. Pharo discarded much more of the underlying machinery so I would guess it will be more work.
