I think people will view the Amiga over time, in the same way we view a classic car (e.g. Mark 1 VW Golf GTI). The Amiga is a classic computer, and will always be loved ;]

i still remember the day uploaded some of these grafix to Zulu also the day downloaded this 2 disks demo, back in 1994 this demo kicked ass, Rebels Rules,

The rebels always had some great stuff. :)

@Sahtzor ... but it won't work on the good old 500. You need at least an A1200 because of the AGA chipset and most likely also specialised code for the 68020 cpu.

demos like this make me wanna go to basement and look for my old'n'dusted A500

Hello, i remember of this demo which was released at a small but impressive (my 1st one) demoparty near Karlsruhe / west "coast" of Germany. I just missed the name (=> Doom'sDay). But it was a fabulous back over 1994.

I will always remember this fabulous experience of watching this on bigscreen. People present were so amazed of that!

@ortega24024 The demo we competed with for the Assembly compo was called Ill Flower. Our group-name was Scum of the Earth (YT does not allow linking to Pouet unfortunately so you will have to search for it there).

@ortega24024 The other optimization made use of setting the screen address in a way that the middle of the screen - the origo or 0 on the Y axis - had the lower word containing 0, i.e. $70000. That enabled faster addressing of the Y-position. Hope it makes sense. Will have to see if I can find the sources some day.

@ortega24024 Thanks! Still far from the 2000 that you succeeded in. From the back of the mind (it's been almost 20 years) the matrix calculations had been reduced to one move followed by 2 adds for each rotation. I think PHA used this kind of addressing 0(a0, d0.w), d1. That can be optimized to offset(a0), d1 which is a faster type of addressing. The way to go about that is to use self modifying code which replaces the offset of the instruction.
