Fans of music made with obsolete technology are in for a treat: recordings of a Ferranti Mark 1 computer playing Baa Baa Black Sheep and In the Mood were recently released, and they are thought to be the oldest recordings of computer generated music in existence.
The Ferranti Mark 1 is a commercial version of Manchester University’s SSEM computer (aka Baby), which preceded several more well known computers like UNIVAC and EDVAC. It was one of the first computers that didn’t require a great deal of hardware rewiring to perform different tasks, making it ideal for this sort of purpose. It is not known whether the program was written to play these songs only or for more diverse composition and playback, but the author, [Chris Strachey] was known to be a friend of the legendary [Alan Turing]. The recording was released as part of the Manchester SSEM’s 60th anniversary celebration.
