Good ol' trek was the very first video game I played on the family computer! This was a IMS 5000SX running TurboDOS 1.2, some time in 1983 I think. (Why my father saw fit to buy this thing instead of an Apple II is a question for another day. The best the IMS could do was drive a text-only WYSE-50 terminal at maybe 19200 baud.) Later on, my cousin would dial me into his 3B2 (using Tymnet or Telenet!) so I could play a full-screen variant called "vtrek". I found the vtrek sources on an FTP archive several years ago, but it requires BSD 4.3-style termios, and I just don't have it in me to port it to curses or something more modern.
