(Note that I have removed the former clause #3, the infamouse BSD
License advertising clause. The UC Regents removed it retroactively,
and the latest development versions have removed it as well, so I'm
assuming that is acceptable to Mr. Bostic.)

It was downloaded from ftp://mongoose.bostic.com/pub/nvi.tar.gz, which
seems to be the new home site: ftp.cs.berkeley.edu no longer archives
nvi.

Later: it's now at ftp://ftp.sleepycat.com/pub/nvi-1.79.tar.gz
