The Netatalk 2.0 documentation is fabulous.
' Inside Macintosh: Networking' is a great book. Fortunately, there is still enough reading material out on the 'net to get a feel for it. I had zero experience with AppleTalk networking. However, my objective here was to stay away from IP completely, and focus on pure AppleTalk. Interoperability with TCP/IP was introduced as far back as 1988 with MacTCP and later MacIP ( Wikipedia) which basically piggybacked IP over AppleTalk.
Despite phenomenal rise of the Internet Protocol (TCP/IP), AppleTalk was supported all the way to the 2009 release of Mac OS X Snow Leopard.
