How did you do your taxes before calculators?

Yep, that's me
For many years I did mine with one of these:

I'd do it first with paper and pencil, and then check it with the little adder. I don't know what ever happened to it, but I wish I still had it. I bought our first calculator about 1975, a basic four function that still works. I use a spreadsheet now, but still double check it with a calculator.

I used a slide ruler and a pencil and paper for the math. It was b#tch to go through all those rules, forms, etc and make heads and tails out of it. I basically used the previous years returns and instructions as a template... as much as possible. Now I just use tax software that walks me through it and don't worry too much about what it is doing or why.
 

Years ago the numbers involved were so small that I used a pencil and the back of an envelope.

When I started working I used an adding machine similar to this one and a ledger posting machine similar to the one below.

I had so little money that it took about 10 minutes using pencil and paper.
