DOWNLOADS
The following are some Lisp sources and various binaries that I find useful and am vain enough to think others might as well.

OpenMCL (PPC Version)
Size: 16.6 MB
Original OpenMCL source tarball. Heavily uses AGL, and is not a great candidate for ongoing dev.
Clozure CL (Leopard)
Size: 0 KB
Clozure CL sources. Requires Mac OS X (10.5) Leopard (PPC/Intel_64) to try out.
FFI Database (Intel, Leopard)
Size: 6 MB
Clozure CL interface database files.
Lisp Importer
Size: 575 KB
A minor update John Wiseman's original Lisp Metadata Importer. (32-and 64-bit Universal Binaries)
