Around that time, someone had loaned Lakeside a computer called a PDP-8, made by Digital Equipment Corp. This was 1971, and while I was deep into the nascent world of computers, I had never seen anything like it. Up until then, my friends and I had used only huge mainframe computers that were simultaneously shared with other people. We usually connected to them over a phone line or else they were locked in a separate room. But the PDP-8 was designed to be used directly by one person and was small enough to sit on the desk next to you. It was probably the closest thing in its day to the personal computers that would be common a decade or so later—though one that weighed eighty pounds and cost $8,500. For a challenge, I decided I would try to write a version of the BASIC programming language for the new computer.
