Thank you Casey and Dave for the references to get a working DynaBook Junior image.
It works fine.
A thing which might not be obvious it to download the example stack http://tinlizzie.org/lesserphic2/aboutDBJr%205-Aug.morph in addition, locate it with the file browser and then choose 'load as morph'

Ted Kaehler has done two implementations of DBJr AFAIK, one in Squeak and one in Javascript.
Here's the javascript version (for Lively Kernel)

I had to dig to find the Moshi image, but here's an actual Squeak image
and I think this was the right image -- note that this was a prototype and that some things (e.g. saving) aren't implemented. Also, I can't get it to open anymore, but I think that might be because I don't have a non-Cog VM now? Not sure which .sources file you want but I'm betting it's V3. The file of interest is "Text Field for LObject.zip"

I was really fascinated with both the approach and the presentation he did here. Active essays are cool.
Meantime I have to figure out why I can't open the image. I thought Cog could open older images, but interpreters can't open Cog images. Hmmm.
Casey,
Try an interpreter VM from squeakvm.org. It will run Cog images as well as older Squeak image formats back to at least Squeak 3.6. It runs the image attp://tinlizzie.org/lesserphic2/ without any problem.
