Inspired by a recording of an IBM mainframe computer which Jóhann’s father, Jóhann Gunnarsson, made on a reel-to-reel tape machine more than 30 years ago, IBM 1401 A User's Manual was originally written to be performed by a string quartet as the accompaniment to a dance piece by the choreographer Erna Ómarsdóttir. For the album version, Jóhann rewrote the entire score, and it was recorded by a sixty-piece string orchestra. He also added a new final section and incorporated electronics alongside those original tape recordings of the singing computer.

The first ever pressing of IBM 1401, A User's Manual comes in a deluxe gatefold sleeve, having been reworked by Chris Bigg (v23) from his original design. Pressed on clear vinyl, two live tracks recorded with the City of Prague Philharmonic Orchestra have also been added and are exclusive to the LP version of this release.
