Infocom's games were based on Crowther, after all. I remember porting the PDP-10 FORTRAN to CDC 6000 SCOPE 3.4. I got the source from a friend who was a DEC CE. After converting the source tape, the "save game" was probably the biggest difference in implementation. I used FTN (FORTRAN extended) to do the deed, rather than RUN. After the game had been distributed at CDC SVLOPS, there was a concerted effort by management to purge the thing from all of the permanent file catalogs. Luckily, management never discovered who introduced the game in the first place... So yes, Adventure/Colossal Cave did run on an honest big mainframe. I never played the game much myself, as I had access to the source, so I knew the innards of the game. --Chuck
