SDC: I'm not sure what this means.  The UCLA IMP was installed about 1 Sep
1969, the SRI IMP around 1 Oct 1969, and UCSB IMP. around 1 Nov 1969 and
the Utah IMP around 1 Dec 1969.  I believe all of the links between the
IMPs were working when each IMP was installed.  Thus, around 1 Nov 1969
UCLA, SRI and UCSB were each connected to the other two.  I don't recall
anything special later that month except, possibly, a visit to UCLA by
Larry Roberts.

Hmm... I arrived at UCLA, originally just for the summer, in May 1968.
Vint was already there, as were several others.  I don't recall whether
Postel was already there or joined later.  The above suggests he joined in
December 1969.
