The history of computing could arguably be divided into three eras: that of mainframes, minicomputers, and microcomputers. Minicomputers provided an important bridge between the first mainframes and the ubiquitous micros of today. This is the story of the PDP-11, the most influential and successful minicomputer ever.
A deep dive into the inner workings of the PDP-11, specifically on how to use the machine to do actual computing tasks. I lack the skills to do anything with a machine like this, but they look and feel so incredibly nice.
