AOS (Academic Operating System) was IBM’s version of UNIX 4.3BSD for the IBM RT (RISC Technology Personal Computer). Academic institutions were offered as an alternative to AIX, the usual RT operating system. It seems that there was a later version of the AOS that stemmed from 4.3BSD-Reno, but was never distributed in large numbers.
There is also the Academic Operating System from Scratch by Hirochika Asai, the last commit at GitHub was made in 2016.
His project page says:
“We are developing an operating system for my personal research and practical education. For the academic purpose, this motivation is similar to MINIX, but we do not focus on theories. Our main objective is to provide knowledges on hardware-related programming. This is one of the most difficult and complex parts when we start the development of operating system from scratch.”
