Somebody programmed a 65-year outdated laptop to play Boards of Canada’s ‘Olson’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 infinite and really gradual iPod, too.

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

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

“Whereas these bulbs have been initially supposed to offer program standing info to the pc operator,” Lynch writes, “Peter repurposed 4 of those mild bulbs into 4 sq. wave turbines (or 4 1-bit DACs, put one other manner), 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, however it’s price it to listen to Boards of Canada’s already nostalgic music from a fair older basic laptop.
