Thanks!

Could this be the book?

If so it seems like the companion CD is something called "BMUG'S CD-ROM"

Which led me here:

That CD seems to be public domain (totally legal to download on it's own). But it's 8 years older than the book itself. Can you confirm or deny it being the correct CD though? Gonna try and download it as soon as I can =)

Edit: Wow, seems to be a bunch of PD disks available there, I should really rummage through a bunch.
