# pdp7-unix ## About pdp7-unix is a project to resurrect Unix on the PDP-7 from scans of the original assembly code done by [Norman Wilson](http://www.cs.toronto.edu/~norman/pers/index.html). The scans of PDP-7 Unix are in the [Unix Archive](http://www.tuhs.org/) at [http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/] (http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/) as the files 0*.pdf. ## Current Status Update mid-March 2016: We've written an assembler, a user-mode simulator and commented several source files. We now have these utilities running: as, cat, chmod, chown, chrm, cp, date, ln, ls, mv, stat. We have a working shell with some functionality missing. We have begun work on building a filesystem. Things to do: finish the filesystem creation tool, finish the shell, write the missing utilities, try to bring the system up on a PDP-7 system. We have a [real PDP-7](http://physics.uoregon.edu/outreach/movies/pdplives/) and [SimH](http://simh.trailing-edge.com/) as target platforms. ## Source Tree The code in the original scans are (c) Novell who own the rights to the Unix source code. Everything that didn't come from the scanned files is GPLv3. * /scans holds the unmodified OCR versions of the scanned files * /src/cmd holds the modified source code of the user-mode programs * /src/sys holds the modified source code of the kernel * /src/other holds PDP-7 source code which did not come from the scanned files * /tools holds the source for the tools written to assist the project * /misc holds miscellaneous notes and information * /pdp7parse holds a Java parser for pdp7 source code ## Travis Status
