The Programmed Information Processor-1 (PDP-1) is maybe most recognizable as the house of Spacewar!, one of many world's first video video games, however because 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's fastidiously fed and programmed into the PDP-1 by engineer and Laptop Historical past Museum docent Peter Samson. It's the ultimate product of Joe Lynch's PDP-1.music challenge, 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 really created by Samson to play audio via 4 of laptop's lightbulbs whereas he was a scholar at MIT within the Sixties. He used it to recreate classical music, however 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 manner), 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 must be manually punched into the paper tape that's fed into the PDP-1.
It's a laborious course of for taking part in even the only of songs, however it's price it to listen to Boards of Canada's already nostalgic music from a good older traditional laptop.
