Hi Robert,
I do not remember anyone mentioning an update to the
image, so I
suspect that the original image that came with the book would
be the one to
use.
The most recent VMs for Squeak will probably not run
an image from
that era, but if you are using Linux for the class, it will
not be
difficult to provide a compatible VM.
If the Ready.image is available for download, could
you please give a
link to the download site? I would be happy to take a
look at it and
suggest a suitable VM for running that image.

Dave,
I retrieved the download from here: https://github.com/apress/squeak I grabbed the ReadyPC-05052005.zip. It worked fine on Linux using the latest Squeak v3. It would not work in v4 or v5. I was also planning to use Squeak By Example (which I believe is v4 era) as well as other, more modern examples for a beginner class. Version 3, 4 and 5 are all available for Windows, Mac and Linux. I **could** have students install all three versions (I did that on Linux) but was kind of hoping to avoid that if it was possible to port these images to v5.
The ReadyPC zip file contains the following:
luth.frm Ready.changes Ready.image spider.frm Squeak.exe SqueakV3. sources
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).
Dave
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.
