Thanks Chris. I will look into the things you've mentioned in your email. Am a little spaced out right now. Will look into it and respond soon.

I don't know what you already know, so forgive me when I'm
redundant. <br>
Scratch uses the Morphic UI on a Squeak image with a virtual machine
underneath. The Squeak version is, I think, 2.8 (as opposed to 4.4
which is about to come out) and came out in 2005. The important
difference is that the virtual machine has changed. Modern vms are
closure complete and have a JIT. <br>
<br>
To see Squeak 2.8 when it was released. [7]<br>
For some videos on Scratch from a Squeak perspective [3-6].<br>
An introductory book on Squeak. [8]<br>
Source code on the virtual machines. [2].<br>
The Scratch image that will not work on a modern Squeak virtual
machine. [1]<br>
But will work on a virtual machine from a Squeakland Etoys release.
[10]<br>
As you first expressed interest with how Scratch interfaces with the
hardware you may need to join the VM-Beginners list [9].<br>
