Used to be that components were readily available in electronics parts
stores. Most of these stores have closed now.

Last week I needed to buy an electrolytic capacitor. Los Angeles,
population zillions, has no electronics stores anywhere near me. But I
found some caps - in a local Radio Shack. Their entire supply of components
was in one DRAWER in the back of their store, well out of sight of shoppers.
Good thing that I wasn't picky about the value or voltage rating!

Radio Shack sells plenty of computer-related stuff. But where's their
RADIO-related stuff?
