Class Files from "Berkeley UNIX and ANSI C"

[Robert B. Carleton]

This is probably a stretch. I recently bought a copy of "Berkeley UNIX 
and ANSI C" by Jack Hodges. It's giving me all kinds of flashbacks to 
the nineties when I was using the FreeBSD 1.X series. I'm really 
enjoying it. Are the example files from the book still available 
somewhere? I did some searching and haven't managed to turn them up 
anywhere so far.

TIA,
