Can't help much, but I did write fish and ching.
ching took a string from the input, hashed it, converted into
hexagrams, and quoted a couple of lines of i Ching text . The text
was copied from a book, presumably copyrighted, although considering
how long ago this all was maybe the copyright has expired now...
I wrote fish for my young son -- it played the kids game. Without
graphics it wasn't very compelling. But there is an interesting
story about it. A couple of weeks after the first version, I
realized that if my opponent (e.g., the computer) asked me for, e.g. a
six, and later I drew a six, I should ask the opponent for sixes.
With this small change the game defeated all kids and most adults, and
the game was even less interesting as a result. I ended up putting
in an option to dumb the game back to its original level.
A couple of years later, at a Usenix meeting, I was publicly called
out for writing a game "that cheated". Unless somebody hacked my
code somewhere along the way, the game simply played excellent
strategy...

Here's a list, gathered from the manuals, of stuff that Bell Labs
may not have the right to redistribute, with some (uncertain)
attributions of origin. I did not check to see which of them appear
in
the TUHS archives; I doubt that /usr/src fully covered /bin and
/usr/bin.
This list is at best a first draft. Please weigh in with corrections.
