I am happy to report that SPACE RAID is now available on cartridge for the Intellivision.
It is a homebrew game programmed by Óscar Toledo Gutiérrez. This adaptation comes real close to ZAXXON, offering the 3-D isometric display.
The 1982 release of ZAXXON ( by Coleco/CBS ) for the Intellivision did not have the 3-D isometric display... it was basically a vertical scrolling game.
Right now the game is being sold for $25 plus shipping ( loose cartridge and manual )
