Mike Mayfield’s 1971 Star Trek was a strategy game designed for computers with no graphical display.

While Teensy boards are more than capable of driving advanced graphical displays, PJRC forum member jim lee ported the BASIC source to Arduino with the help of Arduino forum member WildBill, and then added a GUI to provide keyboard input, and … an entire Teensy 3.2-based handheld unit for on-the-go play. The source, available on GitHub, also provides a version that runs on the Arduino IDE’s serial monitor, so that you can try it without any extra hardware.
