What Fred delivered to us the night before Hallowe'en, 1985, was the original prototype. The MI channel was not delivered for 8 months; until then, we had to use the 3380s. That's why Stu had to do the work he did. Mike certainly advertised the availability of SA-attached tapes for his boxes at the one DEXPO I know they attended (i. e., I ran into them there). That was Anaheim, 1986. >>The TENEX pager was created by Bolt, Beranek, and Newman of Cambridge.

Ah, there's the confusion: The *ITS* pager =/= the *BBN TENEX* pager. Now that's not surprising. -- Rich Alderson You know the sort of thing that you can find in any dictionary of a strange language, and which so excites the amateur philo- logists, itching to derive one tongue from another that they know better: a word that is nearly the same in form and meaning as the corresponding word in English, or Latin, or Hebrew, or what not. --J.
