[Simh] PDP-11 Dungeon

[Bob Supnik]

To answer Rich's question: Dungeon was ported to the PDP-11 first, and 
to a PDP-11 without memory management in particular, because that's all 
I had access to at the time.  The demonstration that Dungeon would fit 
in such a small memory footprint led the MIT authors to target the "new" 
hobbyist personal computers of the time and to found Infocom.

To answer the other questions: I have no source code or documentation 
for the PDP-11 versions.  The revision history shows that the PDP-11 
version was revised several times from 1978 to 1980:

3,01-Oct-94    Bug fixes (V3.2A).
3,01-Feb-94    Portable VMS/UNIX version (V3.1A).
3,01-Jan-90    Portable version (V3.0A).
3,18-Oct-80    Revised DECUS version (V2.6A).
3,18-Jul-80    Transportable data base file (V2.5A).
3,28-Feb-80    Compressed text file (V2.4A).
3,15-Nov-79    Bug fixes (V2.3A).
3,18-Jan-79    Revised DECUS version (V2.2A).
3,10-Oct-78    Puzzle Room (V2.1A).
3,10-Sep-78    Endgame (V2.0A).
3,10-Aug-78    DECUS version (V1.1B).
3,14-Jun-78    Public version with parser (V1.1A).
3,04-Mar-78    Debugging version (V1.0A).

Then I dropped it until 1990, when I moved it to the VAX.

The "portable" VAX version incorporates so many VAX Fortran idioms that 
it will not compile under any standard Fortran compiler today.
