Does this bring back memories for anyone around here?http://www.youtube.com/watch?v=X9dpXHnJXaE
I thought it was pretty fascinating myself
During the mid to late 70s I was assigned to the US Navy fleet calibration training facility at NAS North Island (San Diego) CA. Beyond teaching metrology we were involved to a small extent with ATE (Automated Test Equipment) development as well as transmitting and receiving data. We used those modems extensively and I never gave them much thought till now. The last one I saw or used was Circa 1979 before I was sent to Naples Italy.
Brought back memories so thanks for sharing that link.
