Rendezvous: A Space Shuttle Simulation, is an space simulator published 1982 by Interactive Simulations and developed by Titan Computer Products and NASA scientist Wesley Huntress.
Accompanied by a thick "Spacecraft Operations" manual with a chapter on use in the classroom, this flight simulator was marketed as being as educational as it was fun to play.
The simulation is centered around a typical Space Shuttle mission to service a space station. Mission phases include Earth Lift-Off, Orbital Rendezvous, Approach and Alignment and Docking.
It was released for the Apple II in 1982 with positive feedback from reviewers.
