I remember film strips. They always seemed to have been produced by McGraw-Hill Texts. I remember the tinny sound of the audio and the high pitched "bing" that signaled that it was time to change the strip. Invariably, when the students were allowed to run the projector, the picture, beamed on the screen, seldom corresponded to what the audio was saying at the time. Was this a common problem, or was it because my classmates and I were slow?

Do they still make tape recorders, and does anyone still buy them?
