It's hard to believe where technology has taken us. In the early 1970's I had a job in Okinawa as a civilian employee of the Dept. of Army. When I arrived everyone in the office was excited because the post exchange had just got in a shipment of the newly developed Texas Instruments battery operated electronic calculators that had -WOW - like 16 functions. Of course, if you wanted to make a telephone call back to the States you had to get on the schedule forone of the bases long distance lines.
