Random Number seeds, was RE: First computer with real-time clock?

Computer-based ramndom number seed generation: I may at some point remember the machine/manufacturer, but I *do* recall tha one (perhaps Gummint-oriented?) device used a standard radio buried in it somewhere, tuned to a local station, the output of which was digitized and the seeds extracted from that... as I write this, IISTR that it was some kind of crypto-thingy... One of my favorite Random/Chaos devices, is the glass decorative neon 'candle' lamp - it has parallel adjacent metal plates shaped like a small candle flame, and the Neon pressure is adjusted so that the discharge plays over the surface of the plates, giving an orange flickering 'candle flame' effect. Without going into the physics/math involved, these flickers have a quite random period and map completely onto the Chaos domain. I have a couple that I have built to produce low-speed chaos events for triggering Music Apparatus... but a simple timing slicer looking at the output of one of these would return quite random-length numbers for every 'trigger' event.
