Agreed, those days there were things like POTS. hehehe, no way to generate 50Volts on a Mamba Dyno unless you add say maybe 10 black mambas in parallel, with 10 guys peddling at high speed = rotary dial = "hello world"....lmfao! :-)
@Aki - True, but none of us really implemented this - we knew the theory, but never believed it was viable, or so I think :-) I agree it is way below uni level, but the mindeset to serve a need is worth noting.
