9fans, a few months ago, at a friends request, i acquired a copy of a research unix reader and scanned it, and i put it on archive.org.
the pdf and some other formats are available, but the conversion is not very good, so the pdf is the best bet. https://archive.org/details/a_research_unix_reader perhaps it will give curious minds a little insight into from whence plan 9 was begat.
