BoingBoing: Award-winning assembly-language animation running on a classic Mac

This is really impressive. Somebody was able to use assembly-language programming, which basically is speaking directly to the computer’s CPU rather than going through a nicely cushioned programming system, to make an old black and white Macintosh computer do some pretty righteous animation. I never saw the likes of this on any of my old Macs. But then, nobody I knew was doing assembly language!

3½ inches is enough by Unreal Voodoo is the winner of this year’s “oldskool demo competition” at the Assembly 2009, which is “a festival of low-level assembly programming.” The video is apparently of the animation running on an black and white Mac. From the looks of the computer in the animation, it’s probably a Mac Classic, which had a blazing-fast 8 MHz Motorola 68000 processor. (Actually, Wikipedia says the Classic “was up to 25 percent faster than the [Mac] Plus,” which had the same CPU. A newer bus architecture in the Classic would help everything go faster. So that makes sense. The Mac in the video could also have been a Mac Classic II, which sported a 16 MHz Motorola 68030 CPU. Unlike its predecessor, the always-superior Mac SE/30, the Classic II had 16-bit data bus, which handles less data than the SE/30’s 32-bit data bus. Weak!
