the first examples of rasterbars on the c64 and the amiga
here's an idea: could we collectively try to find the first example of a rasterbar in a c64 demo?
this idea came from a now-closed forum thread that brought up an interesting question:
* did rasterbars originate on the amiga?
this hypothesis is based on the idea that the amiga's copper makes it easy to produce rasterbar-like effects.
i figured we might want to dig deeper into this question. my personal understanding was that rasterbars started on the c64, but this is only because i myself started on the c64 and haven't really been active on any other platform. so maybe i've been wrong all along, and rasterbars started on the amiga?
so let's try to find the earliest instances of rasterbar effects that we can find!
here's is what i did: i did an advanced search on csdb for c64 demos released between 1982 and end of 1985. this did not turn up much - it seems like there weren't that many c64 demos released this early.
there are plenty of c64 crack intros on csdb from this time though. but not that many that seems to show rasterbars. but here are a few that i found:
* Intro 6 (csdb release date 1985)
* Intro VII (csdb release date 1985)
* Intro VIII (csdb release date 1985)
* Danish Elite Intro (csdb release date 1985) <--- pretty lame rasterbar, but close enough
and then there are some early games that used rasterbar-like effects. the one i remember myself from back then is alleykat by andrew braybook, which was seems like it was released mid 1986. video here: https://www.youtube.com/watch?v=jV-E_gnzonw&ab_channel=MontyMol.. where we can see rasterbars behind the text in its intro.
the amiga was released in mid 1985, so those intros and games were released after the amiga hardware was available. but that doesn't necessarily mean that copper bars were done already.
does anyone have any more examples? and could anyone find examples of early amiga demos that display rasterbars/copperbars? |

ok so this is what we have so far:
* hedning found an atari 2600 game from 1982 with rasterbars
* fungus found juice! for the atari 800 from 1983, with rasterbars: https://youtu.be/7oNYUm_oNXk?si=GFzXKuxl-ATu5qVL&t=15
* theryk found attack of the mutant camels for the atari 800, also from 1983, with rasterbars: https://youtu.be/tMmBktfP3jQ?si=bYJcKVkn7JYrE8CI&t=1
this, and the lack of early amiga demos with rasterbars, would refute the hypothesis that rasterbars originated on the amiga.
the earliest rasterbar on the c64 is still an open question though. the feinbein intros linked in the first post are from 1985 and have, in my opinion, the most rasterbar-like rasterbars of raster effects we've found from 1985. they could be misdated though. |

Oh. The Amiga boiz would hate having been beaten by Atari. Better find another platform that is earlier. ;) |

Why though? The Amiga is nothing more than a 16bit Atari XL ;) |

Here's a video of the mentioned Adventures of Tron (1982) from M-Network... https://www.youtube.com/watch?v=MCPrp4KASGY
And: here's the 1977 Air-Sea Battle (atari 2600) with full screen rasterbars. They might qualify?  . |

Juice! was also released for the commodore 64 in 1983.
Looking through old games, Skramble has raster bars in the logo as well. This was also released on c-64 in 1983. |

All graphics on the Atari 2600 is a kind of rasterbar effect. You had to change graphic and sprite data each line to have it resemble something that can be called graphic. It's not the trick, it is how the thing was designed.
The idea that rasterbars originated on Amiga is so ridiculous i'm surprised that you followed that trolling at all.
But it's interesting where rasterbars were first used on c64. |

Yes, they had to "race the beam".

@Jetboy Well, atleast in the original thread I was wondering about the rasterbars, sprite multiplexers and raster based effects in general and if they became part of the demoscene or "protoscene" effect screens after they were done on Amiga. Of course there were earlier examples of them too.
But I think the hypothesis is now proven to be false, and there has been so many different forums and scenes affecting each other, that such clear generalization can't be made atleast. |

Seems nigh-impossible to find anything qualifying as rasterbars released pre-1985. The splits are just too far apart.
While searching, i stumbled over some rather impressive very old demos, however:
Holyhalter 1 (through 5)
Der Schnelle Hut
Four Seasons

How about this?
Skyline Software Systems presents Graphics (1984) earlier than amiga got released, much earlier than Amiga got into the masses. |
