Super Nova was based on the very popular arcade game Asteroids, which was released by Atari in 1979. It was the first big success for Bill Hogue and Big Five Software.
Originally, Super Nova was available only on cassette tape. It required a Model I with 16K and Level I or Level II BASIC. Later, Big Five Software sold a disk version which saved high scores and required a 32K Model 1. They also sold both cassette and disk versions for the Model III.
was based on the arcade game Berzerk
, which was released by Stern Electronics in 1980. The game concept itself is older than that, and can be found in any number of BASIC games, such as Chase
, and Daleks
. Robot Attack
was notable as the first talking game released by Big Five Software. The game supports the TRISSTICK and Alpha Joystick, but not the original STICK-80 (unless you perform a hardware modification to it). In my opinion, it makes the best use of the joystick of any TRS-80 game.
