I agree -- Radio Shack was a decent place to shop for electronic goodies, even when there were other electronics stores around the area, but by the '90s they'd changed their focus so that nearly the only thing I could use them for was certain parts (audio or video cables and adapters, resistors, Minimus 7 speakers, etc.). In 1977 they introduced the TRS-80 microcomputer, and in 1978 I bought one (the Model 1, but at that time the only one). I still have it, along with the computer desk they'd designed for it (with cutouts to allow the various parts to fit with a place for connecting cables).
But, as others have said above, the last few years I could almost never find what I needed in there -- a shame for what used to be a very useful shop for me and many others.
