The Computer History Museum’s Donald Knuth digital archive project  (http://www.computerhistory.org/collections/catalog/102726297 <http://www.computerhistory.org/collections/catalog/102726297>) contains a scan of a listing of the source code of the THE Operating System by Bron, Dijkstra, et al. The finding aid for the collection is here: http://archive.computerhistory.org/resources/text/Knuth_Don_X4100/PDF_index/KnuthDigitalArchive-Index.html <http://archive.computerhistory.org/resources/text/Knuth_Don_X4100/PDF_index/KnuthDigitalArchive-Index.html> — scan down for “Source code of the THE Operating System”.
