Atari 2600

No frame buffer, 128 bytes of RAM and 76 cycles a scanline. The program draws the picture while the beam is already on its way, which makes it the hardest console ever sold and the best teacher of what a cycle costs.

Klakwall

A bat, a ball and a wall of bricks that will not wait. Every two and a half seconds the wall takes a step down the screen, and when it reaches the bat the game is over.

Tunnelkin

A digger in a mine twice the height of the screen. The map lives in the console's 128 bytes of RAM, so every tunnel he digs stays dug, and the window scrolls to follow him a scanline at a time.
