They kept in mind how a set of correctly executed operations **literally** sounded like and therefore they were able to detect errors in later executions when something sounded "wrong". This was way more easy than looking at the light panels commonly used for similar debugging activities, as listening to sounds does not force you to be in a particular place, looking at a particular object. As explained in the interview, an interesting side effect of this hack led to the early computer music experiments with Pietro Grossi (a real giant in contemporary and electronic music) that ended up in the recording "GE-115 concerto" 7 inch vinyl, distributed as christmas gift to all Olivetti/General Electric employees in 1967. here's the link to a webpage with the interview (in italian) https://binart.eu/ge-115-concerto/ and to the recording itself side A: https://www.youtube.com/watch?v=CXosSsSekaU side B: https://www.youtube.com/watch?v=bf8jMA_zizc ...so, what does this curious anectode say to us? it looks like history is on the side of this patch :-) hope it gets in the mainline code!
