 Cool. I know that Infocom did publish ZORK I for RT-11,

myself. 
At one point they had RT-11 versions of most of their games.  I bought a
copy of Sorcerer from them (for $35) a trillion years ago, and disassembled
and commented it.  I later tried to use it to play Hitchhiker's Guide
(which was never released for RT-11) but I think it was a microscopically
different version of the Z-machine so there were problems.
