Ah, thanks, I had the same issue, should've thought to include that.
While I'm commenting: I think the (original) title undersells the significance - the recording is from Turing's computing lab at Manchester, 1951.

> It was a challenge to write routines that would keep the computer tolerably in tune, since the Mark II could only approximate the true pitch of many notes: for instance the true pitch of G3 is 196 Hertz but the closest frequency that the Mark II could generate was well off the note at 198.41 Hertz.
There are several notes that sounds significantly out of tune, a bit similar to a beginner violinist. Which is kind of poetic in a way. The first computer to play music (in 1951!) had not mastered it yet.
It’s truly fascinating that it was out of tune because of the similarities of the Mark II timing with sound itself .. but that also computing rapidly, rapidly started operating in a much higher frequency band and is capable these days of bending audio realities in other astonishing ways ..
