Do you mean the Talos II User's Guide? The other documents are not specific to Talos II as far as I can see.

> Amiga(ish) machines don't have this.

Of course they do have user's guides. Which one are you looking for in particular?
(And of course there's also extensive documentation on the processors used on "Amiga(ish) machines".)
