Here are couple of other sources for really old Csound sources that I found
some time ago:

Not sure of version -- dates of files are Mar. 10, 1994:
ftp://ftp.uni-potsdam.de/pub/systems/sgi/misc/Csound/

The name of the file says that the date is Feb 19, 1988:
ftp://ftp.ucsd.edu/midi/software/csound/
