[ih] Fwd: As Flag Day approaches at CMU

[Clem Cole]

The early maps show the CMU IBM 360/67 running TSS, but I was a programmer
in that shop.  I don't think we ever had an NCP that worked with TSS.  It
certainly was not on the ARPANET when I was a programmer.   However, I note
that later maps, the fourth port on the CMU IMP starts to show it as
C.mmp.  Guy Almes might remember if that was ever active.
