The Commodore PET was one of the first popular pesonal computers, debuting in 1977. Graphics were monochrome and sound monophonic. A large number of games were written for this platform, including the fully one-button game "Air Attack".
To play "Air Attack" you will need to use a Commodore PET emulator such as WinVICE and the "air_attack.prg" file game file. You can use the SPACE BAR to play (or set your controller up to act as the SPACE BAR using the likes of JoyToKey).
Air Attack (1979 Supersoft) was part inspired by Atari's Canyon Bomber, but this time with a more desperate premise...
Press SPACE BAR to drop bombs to clear a path to land your plane which will crash land otherwise.
LEGAL NOTICE: Many game ROMs remain the copyright of the original owners who may or may not be happy for them to be played under emulation. Put in the context of these games impossible to play in their original format for some disabled gamers and I would hope that attitudes would be more relaxed. Support developers by letting them know why you can't play their games and offer some solutions.
