The assembly language that I learned in class was PDP-11. It is an interesting architecture as the machine language is human understandable (to a point) such as the only difference between an add instruction and a subtract instruction is that one bit is 0 (for add) and 1 (for subtract).

Most of the unique pointer math of C happened because they mapped directly into PDP-11 assembly language, such as var++ or *var++ or --var etc.
