DLT? I first heard it as a station wagon full of (9-track, 1600 bpi,
that having been the state of the art) mag tapes on the Taconic Parkway,
circa 1970. I suspect, though, that Herman Hollerith expressed the idea
about a stage coach full of punchcards, back in the 1880s.

The earliest reference to this I've been able to pin down is Andy Tanenbaum's,
and TTBOMK -- and you of all people should know this, Steve -- he was talking
about Usenet, which a few sites actually *got feeds of on magtape*, in the
very early 80s.  Some of those tapes, in addition to UTZoo's backups of their
spool, constituted the very earliest material given to Dejagoo.

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.)
