Yes, I know that story. I'm talking what was said to me personally -- =
not
hearsay, earwitness evidence. The road mentioned was the Taconic =
Parkway, part
of the direct route between where I was working at the time (IBM Watson =
Lab #2,
http://www.columbia.edu/cu/computinghistory/watsonlab.html) and IBM
Yorktown -- =

The context was the speed of an RJE link between the IBM 1130 I was =
running
(http://www.columbia.edu/cu/computinghistory/1130.html) and a mainframe
in Yorktown. (If memory serves, it was a 2400 bps half-duplex link, =
probably
via a Bell 201 "data set". I don't remember for sure, though. Anyway, =
that
was my first contact with networking, though I worried more about the
host part of it. I did learn bisync rather thoroughly in my next gig,
at City College of New York Computer Center, at that time the central
computing hub for the entire City University system.)
