Where can I find documentation for ComputerCraftEdu?
You're confusing two different games here: "ComputerCraft" is a modification for "Minecraft Java edition", while "Education edition" is a variant of (and partially included in) Minecraft Bedrock edition/Pocket edition/Windows 10 edition/… (it has many names, very confusing). MCJava and MCPE are two different games, sharing no code and nothing of either is compatible with the other (mods, resource packs, world saves, …).
I haven't heart about "ComputerCraftEdu" before, but there are only really two possibilities:
- It's a variant of ComputerCraft for education purposes, but still for Minecraft Java edition, then its scripting is probably similar or identical to the normal ComputerCraft mod and only the GUI is different.
- It's a complete remake of the mod for Bedrock edition (I don't know if MCPE mods even exist), then it might have similar scripting, it might not. If you can't find documentation for it, I recommend using the regular ComputerCraft for MCJava. I heard that the scripting it pretty straightforward and easy to learn.
ComputerCraftEdu is definitely not the same thing as "Minecraft Education edition", ComputerCraft is a third party modification while Education edition is an official Mojang product.
Also, whenever a website is not available or working anymore, I always recommend checking https://web.archive.org. The link you mentioned was for example saved there 69 times over the years, 37 of them appear to be working fine (I didn't try the Flash player bits), this is the latest of those: http://web.archive.org/web/20161126140402/http://services.minecraftedu.com/wiki/ComputerCraftEdu
