The kit was never sold to consumers, schools only. So there were limited numbers and not much information. This was the best I could find:

My memories of it are a little fuzzy. I only got to use the system for 1 year, when I was nine years old. There was no assistance, I had to open the Apple and set up the driver card myself, taught myself logo too. I spent every recess inside just to get more time on it. (The kit went to a different school every year.) Unfortunately I didn't grok algebra until the following year, so my programs were essentially simple lists of commands with no math and (at most) limit-switch logic.
