Trek73 is one of many Star Trek simulations now available.
 In its time, it was considered one of the best.

 The player takes on the role of a starship commander who
 is involved in a battle against enemy alien ships.

 At your control are the ships' massive warp engines,
 its main weapons, the phaser banks and photon torpedos,
 and its defensive set of shields.  Using these and your
 own ingenuity, you must form and implement a strategy
 that will lead you to victory.

 Authors:
    William K. Char, Perry Lee, and Dan Gee wrote the
    initial TREK73 in BASIC.  Dave Pare and Chris Williams
    translated the BASIC into C.  Jeff Okamoto, Peter Yee,
    and others corrected and enhanced the code.

 License:
    None included in the package. But I believe it was
    originally under some open license since it was created
    in 1973.
    
    This game came on CohWare Vol 2 from Coherent OS.
    I updated it to compile on modern UN*X Systems.
