This is a set of articles and ads about magnetic tape.
First is a futuristic prediction about how we’ll use magnetic tape to run our robots. This item is brittle and will probably not last too long. It should be archived.
Second is an article explaining how to care for reel to reel tape recorders. Again, brittle.
Third is an ad for the Magnetic Tape Selectric Typewriter, and early word processor that used magnetic tape as its memory, and was an electromechanical computer. This is from the 1960s, to put things into perspective.
Fourth is an ad for a cassette recorder that also has a radio. This was presented mainly as a recorder, but similar devices would be popular in the 1970s and 1980s, and they would be called “boom boxes”.
