Developer Builds C Compiler and Web Browser From Scratch for Obscure Am29000 Chip
A developer has documented an ambitious personal project: writing a C compiler and a basic web browser for the Am29000, a RISC processor architecture built by AMD in the late 1980s that largely faded from use decades ago.
The write-up walks through the technical hurdles of targeting such an obscure instruction set, including handling the chip's unusual register windowing and building out enough of a standard library to make real software - like a browser - actually runnable. Since existing tooling for the Am29000 is scarce or outdated, much of the work involved building compiler internals essentially from first principles.
The project is a hobbyist deep-dive rather than a commercial effort, but it stands as a detailed case study in retrocomputing and low-level systems programming.
