Under The Hood Of Second Reality, PC Demoscene Landmark

In 1993, IBM PCs & clones were a significant but not dominant fraction of the home computer market. They were saddled with the stigma of boring business machines. Lacking Apple Macintosh’s polish, unable to match Apple II’s software library, and missing Commodore’s audio/visual capabilities. The Amiga was the default platform …read more

A Jaw-Dropping Demo in Only 256 Bytes

“Revision” is probably the Olympics of the demoscene. The world’s best tiny graphics coders assemble, show off their works, and learn new tricks to pack as much awesome into as few bytes as possible or make unheard-of effects on limited hardware. And of course, there’s a competition. Winning this year’s …read more

Get Compressed Air From Falling Water With The Trompe

If you’re like us, understanding the processes and methods of the early Industrial Revolution involved some hand waving. Take the blast furnace, which relies on a steady supply of compressed air to stoke the fire and supply the oxygen needed to smelt iron from ore. How exactly was air compressed …read more

The Mother of All Demos, 50 Years On

If you’re like me, chances are pretty good that you’ve been taught that all the elements of the modern computer user interface — programs running in windows, menus, icons, WYSIWYG editing of text documents, and of course, the venerable computer mouse — descended from the hallowed halls of the Xerox Corporation’s Palo Alto Research Center in the early 1970s. And it’s certainly true that PARC developed these technologies and more, including the laser printer and object-oriented programming, all of which would grace first the workplaces of the world and later the homes of everyday people.

But none of these technologies …read more

Apple II Megademo Is Countin’ Cycles and Takin’ Names

The demoscene is an active place to this day, with enthusiasts around the world continuing to push the envelope as far as the capabilities of machines are concerned. [Deater], along with a skilled team, produced this Apple II Megademo which won first place at Demosplash 2018.

The demo starts with an intentional tease, with an emulated C64 BASIC startup screen which splits to reveal the title card. White-on-blue text isn’t the easiest on the Apple II, due to palette limitations, but it’s necessary for the joke to work. The following scenes make heavy use of mode-switching techniques in the middle …read more
