Zaxxon/Versions

Apple II
Developed and published by Datasoft in 1983.

Atari 2600
Developed and published by Coleco in 1982. Does not employ an isometric view at all. Instead, the gameplay is presented from an "over-the-shoulder" view behind the ship.

Atari 5200
Developed and published by Sega in 1984. Identical to the Atari 8-bit computer version.

Atari 400/800/XL/XE
Most likely developed in-house by Sega. Published on cartridge by Sega, and on floppy disk and cassette tape by Datasoft in 1983.

ColecoVision
Developed and published by Coleco in 1982. The only accurate version developed by Coleco (The Atari 2600 and Intellivision conversions differ dramatically from the arcade in their presentation).
