Amazed to see it's still going, I haven't heard mention of it for decades. It was going to be the next big thing around the same time that quadrophonics was failing to take off. Obviously that didn't happen. :) It was developed by the long defunct UK National Research Corporation that also brought us carbon fibre and the hovercraft.
