The Atlantic has a short piece on some signs of fearing computers back in the 1980s.
Mostly these tidbits appear in journalism and popular books. Examples:
"The most important thing to remember about computerphobia is that it's a natural reaction to something unfamiliar,"
"fear of breaking the computer, fear of losing power, fear of looking stupid, and fear of lacking control."
"fear of physically touching the computer or of damaging it and what's inside it, a reluctance to read or talk about computers, feeling threatened by those who do know something about them, feeling that you can be replaced by a machine, become a slave to it, or feeling aggressive towards computers."
How much of that is alive today?
And here's an interesting bit of comparative technology fear:
In 1985, The New York Times suggested watching computer tutorial videos on television—a less threatening screen than a computer monitor for those who were used to TV but new to computing. ("And unlike the more common floppy-only interactive computer programs, these, with their familiar video images accompanying the lessons, help to make personal computing comfortably commonplace...")
You can see tv receding from its position as boob tube to becoming a comfort.
