[ih] Fwd: As Flag Day approaches at CMU

[Steve Crocker]

IIRC, UCSB , Arpanet node #3, had an IBM 360/75 running OS/MVT.  Prior to
being connected to the Arpanet they had a long-suffering attempt to add
interprocess communication to operating system so two partitions could
communicate with each other.  As I understand it, they never got it
working.  However, when they connected the machine to the IMP, two
partitions could communicate with each other by treating them as processes
communicating over the Arpanet.
