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?

Might as well have originated from the various 8-bit Atari platforms that preceded the c64, or arcade games. I don’t think the Amiga was the major inspiration here. Not for me anyway.
Yes, i was just trying to find an early Atari 400 demo with rasterbars. Also pretty easy on that platform compared to C-64, and it precedes the C-64 by a few years.

Isn’t there a raster bars startup logo on the 2600? Never had one of those myself.

did a quick look around at pouet.net for early examples of amiga demos with rasterbars, but didn't find much there either. the first amiga demos / intros seem to start showing up in 1986. here are the ones i found:

* https://www.pouet.net/prod.php?which=6553 (december 1986)
* https://www.pouet.net/prod.php?which=55456 (1986)
* https://www.pouet.net/prod.php?which=55451 (1986)
* https://www.pouet.net/prod.php?which=55449 (1986)
* https://www.pouet.net/prod.php?which=18938 (1986)

with this, i am definitely inclined to your position @tlr, that rasterbars most likely started not on the amiga, but elsewhere such as arcade games. it is pretty easy to find arcade games with rasterbar-like color effects. quick find here, super hang on by sega from 1987, with rasterbars in the sega logo and rasterbar-like colors in the main logo: https://youtu.be/VtP_3ENHFVY?si=0p0wgCm2wnEc1HTM

There were a lot of stuff by the likes of Ratt/Crowther, e.g Ratt Demo IV, and Omega Man/TCS, e.g Omega Demo 3. These were an inspiration to me at the time.

That Dropzone has definitely captured the Eugene Jarvis Aesthethic! Also the Robotron 2084 has pretty rasterbar-ey effects in it.

Yeah. I came here to point out the Atari 2600, but it has already been pointed out I see.

Forget about the Amiga.

Here's Adventures of Tron (1982) from M-Network, for example.



But sure.. it does not answer the question in question. :P "the first example of a rasterbar in a c64 demo". Looking forward to some more answers.

I just bounced into this, January 1986: The Yak Society Intro 2.

I don’t know if this qualifies:
The Dynamic Duo Intro
1985.

...

Certainly not, though it's offtopic to mention (as only C= was asked for by trident) that Atari 800 was very suitable for doing rasters due to that pallette of 256 colors concept...



dates from 1983

Here's a video:

One of the few which always looked way cooler on Atari than on C=64 imho.

But even on C64 there was 'some' raster approach in the sequel from early 1984 Revenge of the Mutant Camels but only in the title screen iirc
