Named ttt, it seems to accept numbers as input, and respond back with
numbers.  Perhaps those numbers are 3D coordinates in a 4x4x4 tic-tac-
toe game.

As Phil pointed out, when it's named dt* (dttt?), it displays four
boards stacked on top of each other.  It seems to use the push buttons
and light pen for inputs.  Maybe also typing Enter.  I haven't figured
out how to play a game.
