1.1 Requirements

Psyco requires:

A 32-bit architecture. A Pentium or any other Intel 386 compatible processor is recommended.
Linux, Mac OS/X, Windows, BSD are known to work.
A regular Python installation, version 2.2.2 or up. Psyco is not a replacement for the Python interpreter and libraries, it works on top of them.

Psyco is not strongly dependent on a particular OS. Precompiled binaries for Windows are contributed by users. Compiling on Linux, Mac OS/X and other Unixes should be easy.

Psyco has an emulation mode that allows it to run on other 32-bit processors but the speed benefits are not big in that case. Psyco does not support the 64-bit x86 architecture, unless you have a Python compiled in 32-bit compatibility mode. There are no plans to port Psyco to 64-bit architectures. This would be rather involved. Psyco is only being maintained, not further developed. The development efforts of the author are now focused on PyPy, which includes Psyco-like techniques. http://codespeak.net/pypy/
