Since PCM audio DMA wasn't really common on STE back then, this issue was not at all documented and most people didn't even know they could ask for an IC exchange (which was possible).
So far all STEs that I tested are okay, but not my Mega STE.
So at last it explains why I had those nasty audio clicks when I coded my VGA intro on Mega STE.
So I found a new thing that was poorly documented on the Atari STE
There are faulty shifters!
(this is the video chipset)
The C300588, found in most STEs, is okay
The C301712 found in Mega STE and maybe later STEs is mostly faulty and generate audio cracks on PCM DMA audio when blitter transfers are in progress.
There is at least 2 revisions of the C301712, the later one seems to be fixed.
The Party was organized by local demo groups: Anarchy, Crystal and The Silents. It was a 99% Amiga party and all major Amiga groups turned up.
During 3 days 1200 sceners gathered (1000 were expected). Most came with their computer & CRT screens!
As you can guess, there was a lot of demos released, and while there was an incredible amount of release each year back then, 3 demos are landmarks in the whole #demoscene.
If you were an Amiga user, you know at least two of them...
Exactly 30 years ago, a huge demoparty took place for the first time in Aars, Denmark:
And... it became legendary in the #demoscene history. (thread)
Sometimes just by swapping a palette's colors you can optimize things a lot... Here -17% on the final file size
