It is supposed to be smaller than conventional memory and hold more as well. It uses magnetism instead of electricity to hold the bit. An official definition is: A type of non-volatile memory composed of a thin layer of material that can be easily magnetized in only one direction. When a magnetic field is applied to circular area of this substance that is not magnetized in the same direction, the area is reduced to a smaller circle, or bubble. After the breakup of AT&T, no more research was done on it. As a result it was too unpredictable and too expensive to use. Maybe if more research is done on it, it can come out in an affordable version? "In order to completely solve a problem, you must make sure that the root of the problem is completely removed! If you leave the root, the problem will come back later to get you." - Norman King

This made it very slow if used as a random access device. It was used in some devices where the sequential stream was appropriate, and I saw some bubble memory units in a surplus store quite some years ago. [link\|http://www.aaxnet.com\|AAx]

Think LCD screen was about 16 lines high. Geetin senile - think it ran MSsssDOS 1.0, but mainly useless as tits on a board. But! - the bubbles indeed stayed in place with power off. Eventually swapped it off to a 'consultant' for another Otrona ;-) A.
