+The first edition of Unix was developed for the PDP-11/20 at Bell Labs by Ken Thompson, Dennis Ritchie and others. It provided a process-oriented multitasking environment with a hierarchical filesystem for about two or three users.
 The source code for the kernel came from a document entitled [[https://www.tuhs.org/Archive/Distributions/Research/Dennis_v1/PreliminaryUnixImplementationDocument_Jun72.pdf|Preliminary Release of Unix Implementation]]. Al Kossow from the Computer History Museum unearthed a paper copy of the document, scanned it in and donated it. The manual pages were OCR'd by Dennis Ritchie.
