Cannot connect to os9 from 10.8.4

After getting a new Mac Pro running 10.8.4, I can no longer connect to my scan station running OS 9.2.2. When I try to connect, I get "There was a problem connecting to the server '10.1.10.40'. The version of the server you are trying to connect to is not supported. Please contact your system administrator to resolve the problem."

This is an ordinary TCP/IP connection. Is there a workaround? I hate to have to use sneaker net to move my scans!

Thanks!!
