Hi If you do a Google for SIGTOT you head off to another bunch of people who hook RNG's up to various things. My *guess* is that they likely hooked one up to a computer back in the 1940's...

Actually, that has always been a concern. As far as I know, the first RNG to be connected to a computer was this one: http://phk.freebsd.dk/misc/DASK_rng.pdf And they specifically had to use a Lead-Acid battery as filament supply for the noise diode to avoid EMC issues.
