UPSID

I was talking with Alexandre, who's trying to do the simple to use lang,
and since then I've been trying to find the UPSID data online. Some data
from it is mentioned in one of my books but I can't find the original
data anywhere online, except with a macprolog program that I need a
macintosh to run. God knows why you'd want to write anything in Prolog
but never mind... does anyone know where I can get it?
