Install unix-v1

Unless otherwise noted, file and directory names refer to this repository. Simply execute make. This will do several things. It will build tools/pdp11, tools/mkfs, tools/ml and tools/apout/apout. These tools are required to build the filesystems for 1e UNIX, and the kernel. It will create kernel sources with some necessary patches, assemble the kernel and build a bootable SIMH memory image which is installed into the images directory. Finally, the make will build the rf0.dsk, rk0.dsk and tape images and install these in the images directory. You can also do a make clean to clean out the images/ and build/ directories. A make distclean will clean out the images/, build/ and tools/ directories accordingly.

The manuals for 1st Edition UNIX are available here: https://www.bell-labs.com/usr/dmr/www/1stEdman.html, http://www.bitsavers.org/pdf/bellLabs/unix/UNIX_ProgrammersManual_Nov71.pdf, and http://man.cat-v.org/unix-1st/. Some documentation of the internals of the 1st Edition UNIX are available here: http://www.bitsavers.org/pdf/bellLabs/unix/PreliminaryUnixImplementationDocument_Jun72.pdf. Details of the PDP-11/20 architecture and its peripherals can be found at: http://www.bitsavers.org/pdf/dec/pdp11/handbooks/PDP1120_Handbook_1972.pdf, and http://www.bitsavers.org/pdf/dec/pdp11/handbooks/PDP11_PeripheralsHbk_1972.pdf. The C compiler from 2nd Edition UNIX is also installed and works, but the language is a very early dialect of C. The closest reference to the language at this point in time is this, but it is probably 2 years too late: https://www.bell-labs.com/usr/dmr/www/cman74.pdf. The userland binaries come from a period somewhere between the 1st and 2nd Edition of UNIX. You may find the 2e manuals useful too: http://www.bitsavers.org/pdf/bellLabs/unix/Unix_2nd_Edition_Manual_Jun72.pdf.
