OS/161
OS/161 is an operating system created at Harvard University, designed as a teaching tool for undergraduate students studying operating systems.[1] It runs on a virtual machine named System/161, which emulates a MIPS R2000/R3000 processor and a memory management unit, but without a floating-point unit or cache.[2] It is used by numerous universities, including the University of New South Wales.[3]
For teaching purposes, many components of the operating system are not included, and are intended to be implemented as assignments by students.[4] Unimplemented components include:
- System call implementations
- A virtual memory subsystem
- A file system with fine-grained locking or journaling.
