Nearly correct. The binary executable was an RSX-11 executable patched to run under Unix V6 and patched again to run under Unix V7; this was what was running on the Vax in compatibility mode with the emulator (which emulated Unix V7, not the PDP; that was hardware). (I did patch it back to Unix V6 to run on a PDP-11/34.) There were more games running in compatibility mode. Later Vax BSD came with an updated (and native) version of Dungeon/Zork. But again later it reverted back to the emulated version. The native version had some extensions, like the Puzzle Room. > Was the full Dungeon source code (in Fortran) ever made publicly available? > Maybe it's at one of the if-archive sites?

In there is the version of Dungeon/Zork as written in Fortran. Adapted to Unix by John Gill... (sp?) and with some patches by me. (There were errors in the original database.) Once upon a time, during a Christmas holiday, I took the RSX-11 binary of Dungeon/Zork, wrote a decompiler, adapted the Fortran to Pascal and implemented the result on a CDC Cyber, with a specially adapted version of the Pascal compiler. Mm, I never seem to do such things anymore. -- dik t. winter, cwi, kruislaan 413, 1098 sj amsterdam, nederland, +31205924098 home: bovenover 215, 1025 jn amsterdam, nederland; e-mail: dik@cwi.nl
