Yeah, I remember bubble memory. It seems like Fujitsu actually got
to work halfway decent. Despite the cost and speed limitations,
Fluke used it in their high-end E-Disk memories for the 1720 series
instrument controllers. SLow, expensive, but for awhile it was about
all you could use for mass storage in certain hostile environments.
