It supports the original processors, G3, G4 etc. as well. Maybe not
the 601? I'm not sure. All the PowerPC ISA Books are in there and
information only seems to have been ADDED (or moved to another
book or been given a new book).

If a processor is not supported it was probably designed and
end-of-lined well before they made the original "Book" specs :D

Have you even looked at it? Even the dumb 'evolution' picture
on Power.org's site makes this quite, quite clear. Most of the
spec is identical, to the letter, over vast amounts of pages.
There are change bars in front of everything that changed and
those that have; it seems they are just lifted and reworked
from Freescale's AltiVec/SPE documentation, reworded in Book E
so you can have a Book E with AltiVec, or has it's own new
book (VLE, which is an IBM-ified copy of the e200 Core
Reference Manual Addendum)
