Here's a link:

On a page:
http://www.spies.com/~aek/orphanage.html
that links to the first, link, the author implies he's got a
work-in-progress emulator started. He has some docs also.
Thanks very much, this is exactly what I was looking for! I should
have thought to ask Al Kossow, I remember now he used to have a huge
collection of Xerox stuff.
The hardware guide is most useful. Now I'd like to find a copy of the
ROMs used in the Alto and Alto II (I can only imagine the copyright
headache... oh well)
