My favorite old pocket computer … drum roll!

…is the TI-66 Programmable Calculator.

It is small and light and Turing complete. The programming records key presses as well as allowing for entering instructions in an assembly-like language, so it is a great primer for learning full Assembly language programming, which is what I am doing now on my HP95LX.
