I still have a copy of the original text game, Adventure, on punch cards. XYZZY, Plover, Plugh, Fee Fie Foe Foo!
I originally played Adventure ("ADVENT") on a PDP-11 (actually an LSI-11) running RT-11 with 8" floppies, and a VT-100 serial terminal. Late 70's.
There are a number of websites (I don't recall the URLs offhand but Google will) that have the original Colossal Cave Adventure running, some of them with a VT100 terminal interface for verisimilitude.
WOW!
Somewhere in a moldy stack of Z-fold in the barn is a copy of a FORTRAN Colossal Cavern game, highly modified by me.
Now thats classic.
I worked for three months in USFK Ration Control on a project. All sales recorded were tabulated in a giant xard reader.
I built my first PC from oarts from the PI, Hapan, Taiwan and Korea in 83. Th motherboard was Apple IIC but I ran DOS. It was a complete a complete bastardization.... it could talk, print, etc. I never knew I would finish my career as a COMSEC manager, and Govt communications exoert. My certifications in Intelligence and Sats, phone exchanges, radio, PTT, DISA Cloud and lo g haul com systems or programming. One if a few with a COMSEC TS desigation among others.
