You know wrong. The main system used was a Foonly F-1, a PDP-10 clone.
Some other hardware was also used, but not a Cray.
The title of the film comes from the TRON instruction of the PDP-10,
one of the 64 logical test and modify instructions. The TRON
mnemonic means _Test accumulator _Right half immediate, set selected
bits to _One, and skip unless all selected bits are zero (the skip
phrase being coded as "N" in the mnemonic):

It has nothing to do with the "trace on" command in Microsoft BASIC,
and the PDP-10 does not have a "TROFF" instruction.
