Default delay line? velocity factor???

Adm. Hooper would bring her wires with her
when she was a guest on the Tonight show with Johnny Carson.

Adm Grace Murray Hooper, a pioneer in practical computing,
and the first woman admiral in the U.S. Navy.




In the early days of computers they used to use a length of wire as
temporary memory. At the start of a store cycle a piece of data would be
input to the wire, after a period of time the data would come out and be
placed into the computation.
Admiral Grace Hopper used to give an example of time and delay in her
speeches. She would say that one day she called down to the computer
department and asked for a micro second. They sent her 1000 feet of
wire. She then called down and asked for a nanosecond, they sent her one
foot of wire. No point to this just a good story.
