Biorhythms + Moon Landing © 1980 Sebree's Computing.
Biorhythms & Moon Landing was a joint release by Cursor and Sebree's Computing. Along with the two programs, it includes a title screen for the tape. Moon Landing is probably the most sophisticated version of a Lunar Lander-style game for the system. After landing, you have to take off and dock with another ship, which is pretty tricky.
