This directory contains a set of documents related to 1st Edition UNIX, along with a working 1st Edition UNIX kernel which was restored from the documents. Documents --------- The man*.pdf PDF documents here are the scanned manual pages to 1st Edition Unix, taken from Dennis Ritchie's web page: http://cm.bell-labs.com/cm/cs/who/dmr/1stEdman.html A copy of the above HTML file is also cached here, but most of the hyperlinked documents are missing. UNIX_ProgrammersManual_Nov71.pdf is a file copied from http://www.bitsavers.org/pdf/bellLabs/unix/. It appears to be an aggregate of most of the PDF documents noted above. The file PreliminaryUnixImplementationDocument_Jun72.pdf, also from bitsavers, appears to be a study of the internals of the 2nd Edition UNIX kernel by Ted Bashkow, done around June to September 1972. We have no other information about the document. Also from the same place on bitsavers is Kernel_Subroutine_Descriptions_Mar72.pdf, which appears to be a preparatory document which formed the basis of Bashkow's study. Working Kernel -------------- A small group of people, led by Tim Newsham and Warren Toomey, have scanned the kernel listing from the above document in, and successfully restored the kernel to working order, using the executables from the `s2' tape in ../1972_stuff. The team's web page is http://code.google.com/p/unix-jun72/. Here you will find a snapshot copy of their work along with some filesystem images: images-20080625.tgz and svntree-20081216.tar.gz
