Amiga Boing Ball on Atari 800 8bit Computer

Most users think, the bouncing ball demo in 1985 was only possible on a amiga computer. But here you can see, the bouncing ball demo was also possible on an Atari 800 8bit computer from 1979 with only 48 kb RAM and a single interrupt. (of course with a lower graphic resolutuion) See also the Atari Fuji Boink Demo with much better graphics than the Amiga ball.

The amiga had atari technology included, since Atari pushed the amiga Corp. in 1982 with the work of many specialists an over 500.000 USD. At this time Atari would use the amiga technology for a new game console. This is why amiga 1000 and atari 8bit computers technical are very similar. (Compare the design/instruction list of the pokey and amiga sound chip, the gtia and the amiga GPU, and many other) But in a dark night Amiga broke all contracts with Atari (retransfer of new technology from Atari technicans) and was bought by Commodore. (see atari-history.com for the original contracts)

Cool

The Amiga and the Atari 800 - two of Jay Miner's finest inventions.

@Gaesatae or perhaps none of us really care what you're talking about, we're just humouring you. Go and grab a multitasking life.

@meowmmmmm grow up. People with lives are way more impressive than you.

[andymerrett]

@meowmmmmm no, what's sad is you talking about your shitty little games when there's a lot more important things going on if only you'd leave your mom's basement once in a while.

Cool :) now comes the time for realtime rendered Juggler ;)

Of course it's not a 3D object it's running a 1.79Mhz 8 bit computer.

From my knowledge of this computer I would say the checkerboard background is built using hardware sprites at 4 x width (Atari's are like Amiga, tall and skinny). The ball is probably built in a series of 2d buffers (One for each frame) and the fine scroll registers and display pointers are used to move the ball (The graphics window is moving over a series of static 2d objects, giving the impression that the ball is moving.

Maybe it's just me, but I think the "bouncing ball" in this video isn't a 3D object. It looks more like a 2D sprite.
