Computer Space pitted a player-controlled rocket ship against two machine-controlled flying saucers in a space simulation set before a two-dimensional star field. The player controlled the rocket with four buttons: one for fire, which shoots a missile from the front of the rocket ship.
During play, two saucers would appear on the screen and shoot at the player while flying in a zig-zag formation. The player’s goal was to dodge the saucer fire and shoot the saucers.
The machine can’t be run through emulation easily on more modern machines because the hardware itself was before the era of arcade motherboards. There’s no RAM, processor or ROM. ROM chips were expensive at the start of the ’70s, so creator Bushnell substituted in diodes on the circuit board, laid out in the shape of the spaceship on the circuit board itself. Interestingly, the highest score possible is 15 — once you go over that, the machine resets.
A game museum in Japan has four of the original arcade machines — and an extra machine to play the game itself.
