Ramada may have been the first / most important customer. But growing up in North Texas where TI sales-people were thick on the ground, I noticed that just about EVERY police department within 30 miles of Dallas had a 990 in the back and 770 terminals up front. I remember writing a check to cover traffic tickets in Cedar Hill and Arlington. Both had 770's and a friend from high school got a job in Arlington running their 990.
