This repository contains a port of the "Ritchie C compiler" to the TI990 series processors, in particular the 9995 and 99105 chips. The port is currently fairly complete; only floating point operations remain unported. Other tool chain components (assembler, linker, etc.) are also provided.

The long term goal is to run ancient unix on these chips. As a first stepping stone on that journey, a port of the original 1983 version of the Xinu system has already been completed. The source for that is also in this repository.

Killed by Google is the Google graveyard; a free and open source list of discontinued Google services, products, devices, and apps. We aim to be a source of factual information about the history surrounding Google's dead projects.

Hyper-linked and cross referenced rendition of the sources, much like doxygen or lxr does it. The desired features were:

cover boot, kernel, networking, library and user level code
cover C, assembler and other relevant languages with syntax highlighting
provide 'what is used where' information, over the whole system
provide hyperlinks for a fast code path analysis, especially across the user,library,kernel interfaces
support to follow the execution logic of a system call starting from user code, through the library layer, through the kernel interface, to the kernel code by just following hyperlinks.

Links to archives for the Bell System Technical Journal, the IBM Journal of Research and Development, DEC Technical Journal, the Hewlett--Packard Journal, and the Intel
Technology Journal.

The long term goal of the Software Heritage initiative is to collect all publicly available software in source code form together with its development history, replicate it massively to ensure its preservation, and share it with everyone who needs it. The Software Heritage archive is growing over time as we crawl new source code from software projects and development forges.
