ITS text files use 7-bit ASCII. Five characters packed per word. Some things like file names use a 6-bit ASCII subset (the range 32-95).
What have you seen from ITS?
Per the link, the file was editted and built on a PDP-10 running ITS, which was a 36 bit machine with an 18 bit address space.
Interestingly, almost everything else I've seen from ITS uses the 6 bit upper-case-only encoding. This is pretty clearly ASCII.
