Now you're thinking what I'm thinking. :) Although, I was interested in the PCB, too, since I figured it might be extra simple. That's a way to reduce cost and improve reliability vs overcomplicated components used in many modern designs. Really, really simple indeed.

Even a modern "advanced" calculator like this 2-line model[^] is just a blob chip and keypad matrix. Calculators are all extremely simple until you get to the graphing ones that have external RAM or even flash memory.
