Cassette support on the PCA somewhat rare and unusual aspect of the original IBM PC (DOS) version is its support for saving and loading games to/from cassette tape, as well as disk. The original IBM PC (and PCjr) came standard with a cassette port - a baseline feature of home computers at the time. Floppy drives were at first optional, but their increased affordability made them ubiquitous very soon after. The cassette port was never supported by DOS (outside of IBM BASIC), and was ignored by virtually all PC software; most manufacturers of clone PCs never adopted it, and IBM itself quickly phased it out, starting in 1983 with the PC/XT.
Unofficial remakeAn unofficial IBM PC/DOS remake of Galaxy (different from the original DOS release) was created in 1989 by Jay Wilt, who had worked on the Commodore 64 port of the game. This version can be played under modern 32-bit Windows editions, with some minor configuration.
