seemed to be no earlier UNIX artifacts except Ritchie’s<BR>
fragmentary code listings on paper. Then in 2006, Al<BR>
Kossow from the Computer History Museum unearthed<BR>
and scanned in a document by T. R. Bashkow entitled<BR>
“Study of UNIX”, dated September 1972 [1]; this covers<BR>
“the structure, functional components and internal operation<BR>
of the system”. Included along with the study was<BR>
what appeared to be a complete listing of an assembly<BR>
version of the UNIX kernel. A second document unearthed<BR>
contained the handwritten notes made in preparation<BR>
of Bashkow’s study; dates within this document<BR>
indicate that the analysis of the UNIX kernel began in<BR>
January 1972, implying that the kernel being studied was<BR>
the 1st Edition UNIX kernel.<BR>
