Attempts at a new operating system and programming language.

This is a work in progress/collection of documents.

To Do

• Add resources to a document folder for easy access to all things operating system related, add git repositories if possible, for a complete history.
• Implement a RISC-V 64 bit core, with an MMU
• Implement a cross compiler for a Pascal/Oberon variant
• Implement bootstrapping tools
• Create a toy kernel
• Expand into a Unix kernel
• Develop user-land
  • Make a TCL like shell
  • Busybox equivalent
  • Compiler for Pascal/Oberon variant
• Turn system into self-hosting one
• Remove cross compiler and bootstrapping tools
• Remove documentation
• Create project documentation
