[edit] Atari 5200 & 400/800/XL/XE

Developed by Atari in 1983. The 5200 version and the home computer version are identical. There are, however, some slight color differences between the two versions, but that may only apply to the PAL version of the home computer program.

[edit] Commodore 64

Developed by Atarisoft in 1983. Later on, the license was taken over by Datasoft, who gave U.S. Gold the rights to release the game in Europe in 1984.

[edit] Commodore VIC-20

Developed by Atarisoft in 1983

[edit] IBM PC

Believed to have been developed by Atarisoft, but it was ultimately released by Thunder Mountain in 1986 using the red/yellow/green color scheme of CGA graphics.

[edit] Intellivision

Prototyped by Atarisoft but never completed. Eventually finished and published by INTV in 1987.

[edit] TI-99/4A

Developed by Atarisoft in 1984

[edit] Vectrex

Developed by GCE in 1983. Another unusual choice of game considering the Vectrex's vector graphics oriented display, but it works surprisingly well.
