Demoscene

Last October, I made the first demoscene production after an almost two-decades-long break — a demo for PICO-8 fantasy console “PICOCHAK: Attack of Donuts.” This article is “behind the scenes” or PICOCHAK.

There is a lengthy history of computer arts festivals, also known as demo parties, held in Russia over the last quarter century. For decades, once in a while people from all over the country gather together to compete in their ingenuity at getting what was once deemed impossible out of the old or new computer hardware and mere bytes of code. A few leading annual events has been established in the early years. One of them, creatively named CAFe (an acronym for Computer Art FEstival), was held in Kazan from 1999 to 2003. It went under the radar since, making the way for the everlasting Chaos Constructions (1999 — now) and DiHalt (2005 — now). After so long hiatus, the last year CAFe made a loud comeback, returning in full glory — at least by the number of prods released, if not in the scale of the event itself. Presentation of the compo entries went far into the night, with the last demos being shown at 6 AM to the popping eyes of the few hardy ones. There was my demo, too, and this is the story of its making.

Known now as a «motherboard speaker», or just «beeper», PC Speaker has been introduced in 1981 along with the first personal IBM computer. Being a successor of the big serious computers for serious business, it has been designed to produce very basic system beeps, so it never really had a chance to shine bright as a music device in numerous entertainment programs of the emerging home market. Overshadowed by much more advanced sound chips of popular home game systems, quickly replaced with powerful sound cards, it mostly served as a fallback option, playing severely downgraded content of better sound hardware.

«System Beeps» is a music album in shape of an MS-DOS program that features original music composed for PC Speaker using the same basic old techniques like ones found in classic PC games. It follows the usual retro computing demoscene formula — take something rusty and obsolete, and push it to eleven — and attempts to reveal the long hidden potential of this humble little sound device. You can hear it in action and form an opinion on how successful this attempt was at Bandcamp, or in the video below. The following article is an in-depth overview of the original PC Speaker capabilities and making of the project, for those who would like to know more.
