Draft:OS/161

Submission declined on 25 May 2024 by ToadetteEdit (talk).

This draft's references do not show that the subject qualifies for a Wikipedia article. In summary, the draft needs multiple published sources that are:

in-depth (not just passing mentions about the subject)
reliable
secondary
independent of the subject

Make sure you add references that meet these criteria before resubmitting. Learn about mistakes to avoid when addressing this issue. If no additional references exist, the subject is not suitable for Wikipedia.

If you have not resolved the issues listed above, your draft will be declined again and potentially deleted.
If you need extra help, please ask us a question at the AfC Help Desk or get live help from experienced editors.
Please do not remove reviewer comments or this notice until the submission is accepted.

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.
