I have VERY fond memories of that game from 1986. My father who was teaching at a community college in Iowa had a copy of that game running on a VAX11. I recall that to play the game he had to walk to the data center and, inside a cabinet, physically unplug the cable for his terminal and plug it into another port. The connector on the cable looked like a large rectangular multi pin monster. Back at his desk, his green screen terminal was ready to play the game. I was 5, it was very awesome.
