Darius,

Interesting!  Might you also have data on when IMPs were installed and removed at Tinker AFB near Oklahoma City and McClellan AFB near Sacramento?

Thanks,

Steve

In this collection I found a folder called "Installation History of first ARPANET Interface Message Processor (IMP) and Terminal Interface Message Processor (TIP) 1969 - 1976" (CBI record).

I don't know what the etiquette of posting them to this list is; I currently only have clearance from CBI for private usage but it's unclear to me whether this (private) list counts as private usage.
