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.
