Well, it was darned near 50 years ago, so I can only recall what was on the DECSystem10 tape, except for very general details. It only took a couple of days to re-work in CDC FORTRAN and I lost interest quickly. I do recall that there were a number of DEC FORTRAN "peculiarities" that had to be ironed out. I didn't even bother to get it working on the CDC STAR even though I had access to resources. I believe that there's even a CP/M-80 version wandering around. I've got a copy of that somewhere. The only other "serious" game I recall fooling with was Chess 3.0 to run under the Zodiac operating system. It used its own peculiar display driver, CHD, which had to be EDITLIB-ed into the system library, because it was played on the DD60 operator's console.. A great time-killer if you've got dedicated block time and are waiting for something to complete. Even on a 6600, it really sucked up CPU time. Of course, now I'm speaking gibberish to most of the audience, so I'll shut up. --Chuck
