Thanks for the high-res link. Surprisingly our computers still do these things, after forty some years. Yet their ancestors did the same job while holding "2,400 double spaced pages or 30,000 names and addresses."
It's funny that Apple calls their computers a "PC".
Was that before the IBM PC?
Yes. It is a weird historical artifact of terminology. We had lots of “personal computers” before IBM made theirs. After that, IBM’s offering became the product most associated with the term. It is a weak example of genericide.
How much longer that list would be today is a little breathtaking.
