The original game that Jaeger developed for the Atari 800 required 48K of memory. Parker Brothers wanted to release the game on cartridge, so they trimmed it down to fit in 16K. One feature removed from the disk version was an unfinished boss fight with a gigantic King Montezuma who can stomp the player character to death.[6][7]
Parker Brothers released versions for the ColecoVision, Atari 2600, and Atari 5200 consoles, and for the Apple II, Commodore 64, IBM PC, and Atari 8-bit computers. To reduce costs, Parker Brothers released the Commodore 64 and Atari 8-bit versions on disk instead of cartridge. In the UK and Ireland, it was also released on cassette tape for the Atari and Commodore 64 .[8] The C64 and Atari versions came on a single flippy disk–likewise for the IBM PC and Apple II versions.
