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? |

The earlier mentioned demo Quote:Skyline Software Systems presents Graphics clearly uses a code that enables changing (border)color each line, as also seen in the code example. Isn't that exactly what is asked for in this thread? Why then start discussing what does and does not qualify as a "rasterbar". A "bar" can be drawn in bitmap-mode or even char-mode depending how many colors you want it to have.. but a "rasterbar" is then probably a bar not drawn by graphics, but created with a raster effect, raster-code, code timed to the blitting raster (damn who asked me to elaborate.. it only gets more blurry). |

Agree with HCL. MobyGames dates Seafox and Choplifter being released September 1983, but probably there were earlier such simple raster effects already?
The reason for mentioning Seafox is that it was the first time I ever saw the border having more than one color, it surely had a wow-factor at the time :) |

Just something I thought of because of this discussion.
The first couple of ATARI 2600 Activision games in 1983 started using their rainbow logo (very rasterbar-ish). https://en.wikipedia.org/wiki/List_of_Activision_games:_1980%E2..
Oink! might have been the first one with it -  |

For some reason I'd like to only define these kind of raster effects as rasterbars :) They are somehow very common on the C64. But yeah ymmv heh

NECROPOST! :-D [Thunder and Lightning intensifies]
Below is a recent video which might be very interesting to understand the dimensions of how large the Amiga cracking-scene phenomenon may/could have been at which point. It sort of matches my wild guess from a while ago.

We should stick to C64 raster, not other systems. I know ATARI is tempting as it used a lot of these effects to show their many colours. But we're C64 freaks, yes?
As for C64 Sirius Software had some early games with stable colour cycled rasterbars inside letters or screen: "Snake Byte" and "Turmoil" and "Wayout". Think they are from 1983. |

We should, but the initial question was to debunk the claim that Amiga was first. Which it was not, of course. |
