I have identified 5 of the 6 games on the movie "Zombie" of George Romero (the scene of video-game playing at minute 01:18:00).
The titles are:
Qwak Atari 1974 Gangbusters, Midway 1974 Night Driver Micronetics/Atari 1976 F1 Atari Namco 1976(first version electro-mechanic) Gunfight, Midway 1975
I miss the last one.
I have two screenshots of it
