Trek73 is a computer space-battle simulation based on the original Star Trek television series. As the name suggests, it was created in 1973 by William K. Char, Perry Lee, and Dan Gee. Many young Bay Area residents played the game on a teletype connected to the LHS DECISION computer located at the Lawrence Hall of Science in Berkeley, California. Roderick Perkins was the one who adapted the program for the LHS computer. Dave Pare and Chris Williams translated the BASIC into C and Jeff Okamoto, Peter Yee, and others corrected and enhanced the code. TREK73 was also played at Wilson High School in San Francisco and Howard Chu ported it to Turbo Pascal for MS-DOS at the University of Michigan in 1985 (where the binary and source still reside) and created a C/curses version in 1990.
