Like most, I loved Radio Shack and found them indispensable for buying board level components for building projects well before the Internet was a "thing".
My first stereo was an "All-In-One" box with separate speakers. It had an 8-track player/recorder. LOL.
But yeah, I knew something was up in the 1990s when all the "real stuff" was relegated to a small area near the back, with lesser choices. My first shortwave was a Radio Shack too. Loved that thing before shortwave started dying about the same time the Internet was borne. Sadly there isn’t much on the airwaves anymore other than a few religious stations from other countries. The "good stuff" went silent long ago.
Oh, yeah, in the early 1980s, a college friend of mine had a TRS-80 running BASIC. We used the heck out of that thing to do our aerospace homework that required a lot of iterations. (Certain equations can’t be solved directly). Good times.

A little bit of a clickbait, but it was a wonderful nostalgia trip looking at all the stuff that people goggled over at Radio Shack almost 40 years ago.
