AFAIK, the first large scale application of ferrite core memory was Seeburg Jukeboxes, from '55 onwards. Yes, 1955. The V and VL were the first. Really cool system...

Wow - ferrite core memory in a Jukebox - would not have guessed.

I seem to recall that the more exotic ferrite memory in computers had to be heated to the proper temperature for operation, but I'd guess that in jukeboxes, lower speed and less temperature dependence was the thing.

Yup, my dad has one of the Seeburg jukeboxes with ferrite core memory. It basically used it to store the selection queue, instead of the mechanical switch bank and trip lever most jukeboxes used prior to that.
