The UNIX images available in this repository were obtained from the w11 project (which uses these images for other purposes). You can get them directly here, as well as more information about the project, images, licenses and other data.
The scripts used to simulate the systems using SIMH for v5 and v7 UNIX were obtained from a w11 project repository, which can be accessed here. The original scripts are available under license GLP v3 or later. Modifications in these files were made by me, to fit the purpose of this repository. These modifications are restricted to the same license as the original script. In addition, the general script for configuring the execution environment of versions v5 and v7 was obtained from the project, authored by Walter F.J. Mueller. You can get the original script here. The original script are available under license GLP v3 or later. Modifications in these files were made by me, to fit the purpose of this repository. These modifications are restricted to the same license as the original script.
The port of Version 7 UNIX to the x86 architecture was performed by Robert Nordier. These modifications are released under the simplified BSD license. For more information on all aspects of the distribution, read this file.
All my contributions and modifications (except for material that requires redistribution under the same license, such as the running scripts) are available in this repository under the BSD-3-Clause license.
