Sea Dragon DOS

Sea Dragon is a side-scrolling game for the TRS-80 computer, written by Wayne Westmoreland and Terry Gilman, and released in 1982 by Adventure International. It was one of the most popular games for the TRS-80. Its success on the TRS-80 led to ports to the Apple II, Atari 8-bit family, Commodore 64, IBM PC, and the TRS-80 Color Computer.

The gameplay is similar to the Scramble arcade game, although the ending is more reminiscent of Phoenix.

In 1995, Wayne Westmoreland released the game into the public domain.
