Where can I find the sounds for Ansteig?

[GrUmPyXs4]

Hi, I just downloaded John Petroski's ansteig scenario from the CSC site. But when I read part of the readme it said he made sounds for it. But it is not on the CSC site. Can anyone tell me where to get the sounds?

Thanks

I think the sound files have been lost through time on the internet...
