It is kind of ironic that today, with cheap 3d printers and drones, and even cheap robots, there is a lot of innovation and experimentation that is being done by young people. But Radio Shack is not where to go to buy that stuff, unlike their TRS-80, electronics kit days.
RS used to all carry a full line of Sam’s Photofact repair manuals. I could fix almost any stereo or tv with those to go by.
Radio Shack tried serious advertising in Make magazine to reach this market. Too little, too late, too much of a time warp, I guess
