   But, but, but..... back when I became a ham (1952) in high
   school and went on to engineering school the year after, in the
   era of "cycles" (not c/sec), capacitor values (we were first
   starting to get away from the term "condensers") were specified
   in mmf (milli micro farads) instead of pico farads as done
   today.

   Inductance was always specified in Henrys, but that gave rise
   to a lot of mirth because we had an Electronics teacher named
   Henry who, when he was "having a good time" at our expense,
   would boast that the "Henry" was named after him. :-)
