My personal favorite quote along these lines has always been, "Never underestimate the bandwidth of a station wagon full of quarter-inch tapes." Even thought the oft repeated story behind it may not be totally true, http://www.bbc.co.uk/dna/h2g2/A678576 And of course there are other theories on the origins, http://www.bpfh.net/sysadmin/never-underestimate-bandwidth.html -- Crist J.

For what it's worth, I first heard that analogy -- more precisely, "never understimate the bandwidth of a station wagon full of mag tapes going up the Taconic Parkway" in the 1969-1970 academic year. At the time, IBM had a small research lab across the street from Columbia University; I worked there as a systems programmer for an IBM 1130. One of the major purposes of this machine was to act as an RJE (remote job entry) station for some big mainframes at Yorktown Heights; when we were having trouble getting it working, someone uttered -- more likely, quoted -- that line. This is considerably earlier than the Tanenbaum story, though well after the invention of early modems. (For what it's worth, the modem we were using was probably 2000 or 2400 bps, half-duplex; the link used bisync. And it was BIG.) --Steve Bellovin, http://www.research.att.com/~smb

The classic Compuserve story was they got {Internet} mail before ftp, etc... This mail came via a Telebit Trailblazer link to OSU where Karl Kleinpaste was postmaster, or at least chief guru. Trouble was, CIS users soon discovered: a) ftp-by-mail {It broke your ftp up into mail-sized chunks and mailed you as many parts as needed.. I used to use it for SIMTEL20} and b) certain Swedish ftp sites. By the time Karl got on top of it, the queue had overflowed all available OSU mail disk space and shut down OSU's mail. The nose-high professors had the unmitigated gall to complain about same. Karl had to work fast. The first thing was a CIS mail block. The second was to write off much of the backlog to 9 track tape and drive it across town to CIS where they mounted and loaded same. The only disappointment in this is there is no "turnpike" anywhere nearby Columbus, & I don't know if Karl drove a station wagon. -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
