The Programmed Knowledge Processor-1 (PDP-1) is probably most recognizable as the house of Spacewar!, one of many world’s first video video games, however as the video above proves, it additionally works as an unlimited and really sluggish iPod, too.

Within the video, Boards of Canada’s “Olson” is taking part in off of paper tape that is fastidiously fed and programmed into the PDP-1 by engineer and Laptop Historical past Museum docent Peter Samson. It is the ultimate product of Joe Lynch’s PDP-1.music challenge, an try and translate the brief and atmospheric music into one thing the PDP-1 can reproduce.

As Lynch writes on GitHub, the “Concord Compiler” used to translate “Olson” to paper tape was really created by Samson to play audio by 4 of pc’s lightbulbs whereas he was a scholar at MIT within the Sixties. He used it to recreate classical music, but it surely’ll work with ’90s digital music in a pinch, too.

“Whereas these bulbs have been initially supposed to supply program standing info to the pc operator,” Lynch writes, “Peter repurposed 4 of those gentle bulbs into 4 sq. wave turbines (or 4 1-bit DACs, put one other means), by turning the bulbs on and off at audio frequencies.” The sign from every bulb is then downmixed into stereo audio channels, transcribed by way of an emulator and merged right into a single file that needs to be manually punched into the paper tape that is fed into the PDP-1.

It is a laborious course of for enjoying even the best of songs, but it surely’s value it to listen to Boards of Canada’s already nostalgic music from a fair older traditional pc.
