Yes the schematic is the same.

The UAII book is far more thorough in describing HOW the circuits in the
Apple actually work, rather than just what results they achieve. If you
read it, you will pretty much understand what is the job of every
electron moving around in the machine (with the exception of the inner
workings of the CPU). Really a great reference.

Such a thing is found at the very end of the above-mentioned book ;-)

(Confession: I was the person who scanned it and uploaded it originally.
Thus consider all of this a plug, but an honest one. ;-)
