Buried within the boxed edition of the band’s OK Computer anniversary release is a computer program for a 1980’s computer with a hidden message.
Discovered by a group of dedicated fans on Reddit, the program is for a ZX Spectrum, an 8-bit computer that was popular in the UK in the 1980’s. They noticed that the end of the boxed set’s cassette tape (because of course Radiohead also made a cassette version of OK Computer for the anniversary release) sounded like the startup sounds of a ZX Spectrum.
This quickly fueled speculation that the band, which reportedly used a ZX Spectrum for sound effects on the original release of OK Computer, had hidden a secret program for fans. So, naturally, it didn’t take long before a fan had filtered the audio and ran it through an emulator. The result was a bizarre “radiohead” program, which you can see in its entirety below
Besides the “inside your home computer are… ” introduction, there’s apparently a separate hidden message in black text on the video’s black background the poster says he pulled directly from the program’s code.
“congratulations….you’ve found the secret message syd lives hmmmm. We should get out more”
