There we have it, after a LOT of fighting the emulators, missing bits, LOTS of help the hercules-os380 mailing list, and the EXCEPTIONAL of one Paul Edwards, and it’s running.
It seems to be Dungeon version 1.2C
US NEWS & DUNGEON REPORT
01-MAR-81 Late Dungeon Edition
This is a version of Zork on VM/370
The problems with it are:
-Lack of an endgame.
-Simple parser (no compound sentences).
-Numerous bugs and spelling errors.
But so what.
If you encounter problems or find logic, spelling, or usage bugs,
keep them to yourself.
It’s a little odd playing zork on a mainframe…
