A.2 Obtaining Ptolemy

Ptolemy binaries are currently available for the following architectures: HP running HPUX10.20, Sun 4 (Sparc) running Solaris2.5.1, and Sun4 (Sparc) running SunOS4.1.3. In addition, Ptolemy has been compiled on HPUX9.x, Linux Slackware 3.0, NetBSD_i386, IBM RS/6000 AIX3.2.5, SGI Irix5.3, SGI Irix6.x and the DEC Alpha OSF1 V3.2 platforms. These additional platforms are not supported in-house and thus these ports are not tested and may not be complete.

Installing the full system requires about 150 Megabytes of disk space (more if you optionally remake). The demonstration version of Ptolemy, "Ptiny," only requires 12 Megabytes of disk space. All versions requires at least 8 Megabytes of physical memory.

"Ptolemy mailing lists and the Ptolemy newsgroup" on page A-2 for details.

A.2.3 Obtaining documentation only

All of the manuals as well as a number of Ptolemy-related papers and journal articles are available from the WWW site and from the FTP site in the /pub/ptolemy/papers directory.
