Looking for futuristic short story about a man who brings a new device home called a "computer" which soon takes an increasingly central role in its owner's life to the point of literally reaching out with tentacle wires and pulling him inside/consuming him at the end.
It was written sometime in the 1970s as I read it in elementary school in either 1979 or 1980. I remember being actually horrified at the above visual but took it as warning about the encroachment of/dependency on technology into our lives (crude LED watches were all the rage that year!) and that certain precious things, now considered mundane, could be sacrificed for convenience. And that we'd become dependent and isolated over time.
