Geez Scot, think there would be a market for that book ?? Another book on call-progress tones around the world, etc., etc. There may be money in them thar hills.
No I don't have them all but dstinctly remember the half-wave rectifier once used in Tonopah Nevada, to ring chicken farms over barbed wire. It did not appear in any standards or regulations and UL would have frowned on the installation. However, they did have state of the art IBM billing machines for the chicken farms. Ciao, Vic
