pdp7-unix

This is a project to resurrect Unix on the PDP-7 from a scan of the original assembly code done by Norman Wilson.

Right now the scans are in the Unix Archive at http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/ as the files 0*.pdf. We now need to convert these to machine-readable assembly code, write tools such as an assembler, a filesystem creation tool, and write from scratch missing things like a shell, ls etc.

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 pages are 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

tools holds the source for the tools written to assist the project

misc holds miscellaneous notes and information
