I once worked on a Univac 418-III based message switching system in the late 70s, early 80s that used 18-bit wide (2 x 8-bit words plus parity bit) ferrite core memory. Univac programmers had written software in assembler that allowed ‘music’ to be heard in a transistor radio tuned between stations and held close enough to pick up the electromagnetic noise radiated from the ferrite core memory. I did not hear myself, but a colleague of mine at the time assured me he had heard it shortly before I started working at the site - 1979. Now I am showing my age.
