spectralight mill software help

I have located an old spectralight mill at my school. It seems ready
to go, but is missing software. I am trying to locate some software
that is MAC based for it. Any leads would be appreciated. I need to
be able to show the administraion that this thing is being used before
I go and drop bigger bucks on a conversion. The nill documenttion
dates back to 1990.

Any ideas?

Thanks

Mark
