In 1991, I'd just gotten my first real programming job for two reasons: nepotism, and a willingness to write code for $12/hour. I was working as a contractor to a blood testing laboratory, where the main development job was writing custom software to handle, process, and do statistical calculations on blood testing results, primarily for paternity testing.
My father had been a software developer since the early 1970s, and worked as a contractor at this blood lab since the late 1970s. As the calendar had marched toward the early 1990s, technology cruft had collected. The old TI mainframe, once the primary computer, now only had one job left: statistical calculation for paternity testing, written in TI's Pascal. Slowly but surely, the other software had been rewritten and moved to an AT&T 3B2/600 running Unix System VR3.2.3. That latter machine was the first access I had to a real computer, and certainly the first time I had access to Usenet. This changed my life.
