Personally I would go here:

http://www.ak6dn.dyndns.org/PDP-11/

and look in the TU58 and possibly M9312 directories (the ZZ test ROM I 
have found very useful).

If you get an 'access denied' response it is because by default I 
disable most blocks of IP addresses from outside North America. My 
server was continuously getting bombarded from sites in mainland China 
looking for PHP holes. So by default I closed the door in Apache; email 
me if you want access with your IP address block.
