Parsec is a horizontally scrolling shooter written by Jim Dramis and Paul Urbanus for the TI-99/4A and published by Texas Instruments in 1982.

[1] The player in Parsec pilots a spaceship through sixteen differently colored levels which scroll horizontally across the screen.

Starting with level 4, the Swoopers are preceded by a random number of Killer Satellites, which come without the usual computer warning.

The voice of the on-board computer was performed by Aubree Anderson, who at the time was a student at Texas Tech University.

[3] The speech data for Parsec, Alpiner and Moon Mine was later acquired by Plogue Art et Technologie, Inc.
