MacPython-OSX is plain vanilla unix Python, so popen3() is available.
MacPython-OS9 has no popen3() (or fork, or execve, or any of the other
process calls), and there isn't really any way to add them, as the 
concept
is alien to MacOS9.

There are all sorts of ways you could add similar functionality on
a case-by-case basis, but my first suggestion would be that you drop
OS9 compatibility, because whatever workaround you want to do it's going
to be a lot of work, for a platform that is quickly fading into 
oblivion.
