This is about digital archeology. I hope people interested in the legacy of early online services will find it useful. And I hope other digital archeologists more knowledgable than me will find it and provide additional information. Maybe someone even feels compelled to pick up where I left off? Please bear in mind that this is the work of just a couple of long winter evenings. My knowledge of traditional mainframes and minicomputers was close to zero before I started this project. I might have misconceived things or overlooked others.
