Somebody programmed a 65-year previous pc to play Boards of Canada’s ‘Olson’

The Programmed Knowledge Processor-1 (PDP-1) is maybe 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 gradual iPod, too.

Within the video, Boards of Canada’s “Olson” is enjoying 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 mission, an try to 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 pupil at MIT within the Nineteen Sixties. He used it to recreate classical music, nevertheless it’ll work with ’90s digital music in a pinch, too.

“Whereas these bulbs had been initially meant to offer program standing data 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 approach), by turning the bulbs on and off at audio frequencies.” The sign from every bulb is then downmixed into stereo audio channels, transcribed through 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 only of songs, nevertheless it’s value it to listen to Boards of Canada’s already nostalgic music from an excellent older basic pc.
