It was instantly banned in our physics class when he brought it in, because we had to do everything on slide rules. My kids are still amazed at how fast I can add things up, multiply, or divide in my head--today nobody has to practice that stuff much beyond the early years of grade school. One of my first jobs was in a small convenience store and it didn't even have a cash register. The clerk, me, had to add everything up in my head manually or on a piece of paper if the list got too long, calculate the tax, add it on, write it on the slip, and then make change from a drawer. And you had to do it fast!
My dad still has one of those!!!! It has a 9V battery spot, but also an AC adapter. Wow that brings back memories!
