I suspect that it might be very well be a corruption of the story
about Randy Cook's easter egg in TRS-DOS, that showed up in NewDOS
prior to NEWDOS80. That one really DID exist.  RS, in TRS-DOS 2.3,
changed "Randy Cook" in the easter egg to "Tandy Corp".  It was
invoked by running a boot file as if it were a program, with one
of the master paswords, and pressing 'J'? and 'N'? while it was loading.
