Flash Linux 0.11 Talk
Annotated Unix system source code
flash-linux0.11-talk is an annotated walkthrough of the Linux 0.11 kernel that explains how a tiny Unix-like system boots, schedules, handles interrupts, and manages memory. The materials break down historically compact and dense code into digestible segments, with diagrams and call flows that trace execution from bootloader to user space. By focusing on a small, early kernel, the series reveals core OS concepts without the complexity of modern subsystems. -

Ancient Linux on Windows
Building and running ancient Linux on Windows
While I may have started with Linux 0.11, I've expanded this to include several older relases of the Linux kernel that you can cross compile from Windows, and run on Qemu. I've managed to get the older versions of the software tools running on Windows, so that there is no major invasive source changes, outside of either broken drivers, or massaging the makefiles to find things in the new paths, and calling the appropriate tools where needed. Linux 0.10 is the first oldest version of... -

SpecOS
A multi-threaded-style OS for the Spectrum +3
A multi-threaded-style OS for the Spectrum +3. Based on a kernel/userland model, it decouples the kernel implementation from the run-time system call mechanism, and provides for some POSIX-style functions. A file descriptors layer provides abstraction for easy file redirection. Userland processes are relocatable, and have no knowledge of the kernel or memory layout, leaving the flexibility to change the memory paging model without requiring a recompile of all userland programs.
