You can now find a list of Smap Server versions available for download at http://www.smap.com.au/downloads.shtml. Version13.12 as well as training documents are now available from that location.
Older versions of the server can still be downloaded from the Google code site. https://code.google.com/p/smap-suite/downloads/list. Search for “Deprecated Downloads”.
The download is actually hosted on Amazon S3. This move was required because Google no longer allow new downloadable files to be added to https://code.google.com. Hence the training documents have all been moved to google drive and the large server files to Amazon S3.
