Newcastle Connection Sources?

[Veit, Holger]

Hi,

for some research on ancient Unix, I am interesting in finding the 
source code (tape, etc.) of the so-called "Newcastle connection", aka 
"UNIXes of the World Unite!" . See, for instance, 
https://pdfs.semanticscholar.org/13f8/6c18fa780031d76b80f359d6670f9f3debdc.pdf 
or 
ftp://ftp.informatik.uni-stuttgart.de/pub/cm/pcs/NewcastleConnectionR1.0_1983.pdf 
for details. There are a few more papers which I know as well.

Does someone have the source tape or pointers to it?

THX in advance
