The Tandy 102 is 1/2 inch thinner and one pound weight different. The "Date-Bug" (random changing of the calendar) is also repaired from the Model 100. The Tandy Radio Shack Model 100 was also a big hit with journalists. Another big-time user of this computer was the McDonald's restaurant chain. Until fairly recently every McD's had one of these units hanging in an custom designed "holster" above the heat-lamp trays to track custom orders. A B&W CRT monitor was mounted above the computer.
