The TRS-80 was hardly a gamer's dream; it was designed for "serious" home and business use, though users were hard pressed to find many practical uses for the primitive technology -- a 3 x 5 card and a pencil were still superior tools for most purposes. Radio Shack wasn't quite sure how to market the system to consumers beyond the type attracted by its basic technological appeal, usefulness be damned.
While the TRS-80 was intended to help file recipes and balance the household checkbook, good tools for actually doing so were slow in coming, and most required the additional expense of a disk drive. Many of these utilitarian software packages were promoted with appropriately dull black-and-white one-sheets -- three volumes of Real Estate software, anyone?
It's hard to believe from a 21st century perspective, but Radio Shack's marketers didn't quite grasp the appeal of games as a way to sell home computers. This ad promoting a paltry launch selection of "Games and Novelty Programs" is just as uninspiring as the company's other software promos.
