My husband kept a lot of old engineering-school Stuff for a while, but I finally persuaded him to dump it.
Engineering is a lot like taxes, in that, by the time the printed materials reach the public, they’re already out of date.

That's awful! You never know when you might have to design, say, a circuit using 12AX7 dual triodes, so I still have my trusty old 1960 Sylvania vacuum tube guide on the shelf.

LOL! My Dad used to run a vacuum-tube square-root calculator for Boeing, back in the late 50’s. He said it was as big as the average living room.

After he joined the Navy, he always had a subordinate to do computer stuff for him :-). If I want to communicate, I have to phone or write a letter on paper!
