Nostalgia

I was looking for retro radio examples to draw for the modeling challenge and came across this handy item. I remember having a Chadwick Magic Brain Calculator as a kid. These were sold in 1950 and I was not born until 1969 so this was an "older" item at the time I used it, but I do remember it fondly.
So what things get your nostalgic juices flowing?

Dear Bob,
Thank you. Those are very interesting. I think to make those work well, one must have a very good grasp of the mathematics you are trying to perform unlike electronic calculators today.
