From the FAQ:
CMU Common Lisp is free, and runs on Sparcs (Mach and SunOs),
DecStation 3100 (Mach), IBM RT (Mach) and requires 16mb RAM, 25mb
disk... It is available by
anonymous ftp from any CMU CS machine, such as
lisp-rt1.slisp.cs.cmu.edu and lisp-rt2.slisp.cs.cmu.edu, in the
directory /afs/cs.cmu.edu/project/clisp/release. Login with username
"anonymous" and ·······@host" (your email address) as password. Due to
security restrictions on anonymous ftps, it is important to "cd" to
the source directory with a single command. Don't forget to put the
ftp into binary mode before using "get" to obtain the
compressed/tarred files. The binary releases are contained in files of
the form
<version>-<machine>_<os>.tar.Z
Other files in this directory of possible interest are
15b-sun4-source.tar.Z, which contains all the ".lisp" source files
used to build version 15b for Sparc machines, and
10-16-91-cmucl-master.tar.Z which contains the project/clisp/master
subtree, with RCS source (,v) files for all of CMU CL. Bug reports
should be sent to ··········@cs.cmu.edu.
The above description may be a bit confusing. You first make an FTP
connection to some CMU machine, perhaps one of those listed above. A
better choice is "ftp.cs.cmu.edu", a machine just set up to handle
FTP traffic in CMU Computer Science. (Internet address 128.2.206.173)
THEN you have to "cd" to the AFS directories specified above. Do this in
one atomic operation, since some of the superior directories on the path
are protected against outside access. Then you should have no trouble
obtaining the files. Use "dir" to see what is available. The 15b sources
are now obsolete.
