Technical Documentation Wanted

[Brian Todoroff <btodorof@hmc.edu>]

I am looking for technical documentation on the Apple IIe enhanced 
and the Apple IIgs.  To give you an idea of what I am looking for I 
want information of the expansion bus used in each computer 
(connections, timing, protocals, ect.), addresses for peripheral 
chips, information on peripheral chips (video chips, audio chips, 
serial, ect.)  I am looking for as much detailed information on 
these computers as I can find.  Please let me know about any 
information or sources for information you know about.  Like I said 
I am looking for everything from schematics up.  I also am looking 
for copies of the Technical References for these computers from 
Apple.

Please e-mail me if you have any information at all:
btodorof@hmc.edu

Thanks in advance,
Brian
