Not listed in any official price lists. Special units ordered by corporations, my unit was made for AT&T.

Interesting! One would think anything AT&T custom ordered in the 80's would include a modem... I have at 2 (3?) AT&T branded pods and have just assumed they included modems, but will have to check, now that you've raised my curiosity. Thanks!

Another variation, I presume from the factory, is the presence of an external speaker. Seems pretty awkward for a unit intended to be mobile, but these were early days of mobile computing...
