A Macintosh Boxer -- including documentation, demonstration materials
and tools -- is available for free download.
There are currently no active plans for a Linux version of Boxer. There
is an older version of Boxer available for Sun Workstations running Sun
OS 4.x. (Sorry, at this time, there is no version for Sun Solaris.)
The University of California has prohibited our providing information
about PC Boxer. Seek other sources of information.
