As the Bubbl Bursts

The invention of magnetic bubble memory was once seen as a revolutionary computer development – the wave of the future. It is now a nearly forgotten technology.

“Many persons expect that the most dramatic changes in digital systems will result from magnetic-bubble chips that could well hold a million or more bits in the not-too-distant future. Along with charge-coupled devices, these memories show promise of replacing magnetic tape and disks for small systems.” [emphasis in the original]

One of the more unusual computer objects that I’ve collected over the years uses this memory. It is called the QSB-11A Bubbl-Board. I was told by the person that sold it to me that it had been used in a system at Los Alamos National Laboratory. I have no idea how it was used. Given the nuclear research conducted there I sometimes wonder if I should check to see if it is “hot.”
