Is there any other printed thing (yes, I know a few Web pages have some
content) that anyone knows of that covers them in more detail? (I have a
709/7090/7094 programming thing coming, but that won't cover the internal

Yes, I know, I could look at the engineering manuals, but I was hoping for
something in between them and Bashe et al.
