From Endless loop: A brief history of chiptunes:
Pressure Cooker was an ambitious exception among its contemporaries. In 1980, most home computer music remained limited to single-voice melodies and lacked dynamic range. Robert “Bob” Yannes, a self-described “electronic music hobbyist,” saw the sound hardware in first-generation microcomputers as “primitive” and suggested that they had been “designed by people who knew nothing about music” (Yannes 1996). In 1981, he began to design a new audio chip for MOS Technology called the SID (Sound Interface Device). In contrast to the kludgy Atari TIA, Yannes intended the SID to be as useful in professional synthesizers as it would be in microcomputers. Later that year, Commodore decided to include MOS Technology’s new SID alongside a dedicated graphics chip in its next microcomputer, the Commodore 64. Unlike the Atari architecture, in which a single piece of hardware controlled both audio and video output, the Commodore machine afforded programmers greater flexibility in their implementation of graphics and sound […]
When I saw this headline linked by Waxy I took it to be an overview of the recent (late 90’s to now) chiptune music craze, but it’s actually a nice little overview of the nearly 30 years old history of writing music on game hardware. Even includes sections on cracktros, the demoscene, and the early advent of trackers, along with some good videos of the relevant technology.
