[ih] Fwd: As Flag Day approaches at CMU

[Wayne Hathaway]

An IBM 360/67 running TSS was at NASA Ames Research Center at Moffett Field, CA.  It was host 16 and its IMP was an early TIP..  And i can attest that it DID have an NCP because I wrote essentially all of it! And that was followed by a TCP/IP version just slightly after the switchover date.  I don't know about CMU.
