I could not resist posting pictures of a find I made in a box at home, a pad of IBM 132/10/8 print charts. The numbers denote that the chart is 132 characters wide, with 10 characters per inch and 8 lines per inch. These were used to assist programmers designing reports, and make it easier to translate the desired layout to Output specifications.
My wife had acquired the pad of charts in a previous job many years ago, and had put it in a "safe place" in case she needed them in the future. The charts had been stuffed into box of other old computer items during one of our moves, only to be rediscovered yesterday during one of those "I wonder what's in that box?" moments.
I have not used these in my programming career. Have you?
