The unexpanded Jupiter Ace has only about 1K of user RAM available for programs, but these two demonstrate convincingly what a lot can be done by a skilled programmer within this limitation.

Using a mixture of Forth and machine code, Spacefighter Pilot speeds off down a realistic runway into a flickering galaxy of stars.

Moving lines produce a most realistic sensation of motion until the jump into hyperspace with a choice of two warp speeds, both good and fast.

There are the usual space noises for background, while a running total of missiles zapped or evaded is conspiculously signalled at the bottom of the screen.

The instructions are barely adequate, but the user will sort them out eventually, though if he can operate the one to shut off the space noises he'll do better than I did.

Missile Man has only one gun in this remarkably successful attempt to reproduce something of the traditional arcade game invaders game within the limits of monochrome 1K.
