Dave's right: there were many "untested" technologies that went into the 
ARPAnet and it was expected that there'd be an extended period in which 
it'd be flaky, tests would crash it regularly, etc.  It was a surprise 
that when it was turned on it just kind of worked, which quickly changed 
the focus of the work on it.  There were still experiments run, but the 
emphasis switched to "well, now we've got this damn thing, what are we 
going to *do* with it".

I think the "operational" use came less with military types than with 
"business" types -- clerks, secretaries, etc.  People were doing real, 
routine work over the ARPAnet and very quickly were expecting it just to 
"be up",  Same thing with experiments being run [distributed OS, 
encrypted speech, etc]: the fact of the ARPAnet _just_working_ was almost 
taken for granted.

I can't remember any more [maybe Dave does] but we had something like a 
two hour slot once a week in which we could tinker with the IMP code 
[something like 6-8AM on Tuesdays??]
