Hi Robert,

As far as I am aware, the images that go with these books are not being
actively updated for newer versions of Squeak. But aside from the inconvenience
of installing multiple versions, there should be nothing wrong with using
those images exactly as they are. They should work fine, and by using the
old images you can be more confident that the systems will work as
described in the books.

I downloaded the zip for Ready.image, and the image seems to work fine with
the interpreter VM that I have installed on my Linux PC. This is a VM
that I compiled from latest sources, so I am confident that if the
VMs that you are using with the book distributions do not work properly,
then an updated VM for Linux can be provided (and I would be happy to
help with that if needed).
