Things to Look At has a great post on Vintagecalculators.com. They’ve got plenty of adverts and pictures of old school adding machines. I have an old 70’s TI from my dad I should get it out and dust it off. Jakub also has a couple if I remember correctly.

I have the 16th one down if you count left to right , the khaki one with the white orange and khaki buttons
I have that same one as Jakub, just bought it at a yard sale for $1.
Great roundup of those old machines! The TI machines were pretty robust. I’ve got 2 working TI Datamath models, too, that my Dad used for accounting in the 70s.
