LCM this weekend had a demo of their "Miss Piggy" 11/70 running Unix
v7 (apparently Microsoft's original development machine?) and it
occurred to me to have a quick look at the LCM archive and found this:

[XENIX] Tests basic.pdp 11 util / February 14, 1982.
1 9 track tape with handwritten label.

I wonder what that is? If anyone is going to have XENIX material I
would expect LCM to be a potential source for it.
