That's fair, but it would be no less effective than a similar course based on Linux which would actually give the graduate a far more practical amount of knowledge. Acquisition of knowledge isn't free and to purposefully use a toy when the real thing is freely available for commercial reasons is just grift and AT and VU were well aware of this.

Note that all I'm doing here is taking AT at his word that he developed Minix solely because the source to Unix wasn't free to universities to hack on. They could have adopted Linux from the day that it became available then, or at least the beginning of the next academic year.

I believe in the present day, the premise motivating these undergrad books and courses based on alternatives (VU and Minix, MIT and xv6, Purdue and Xinu, God knows what else) is that Linux has become too complicated for an introductory course. I honestly don’t have any instinct as to whether this is correct pedagogically. I suspect the two main factors are how well the software facilitates getting students situated and in a position to do meaningful programming assignments quickly, and how motivated the students are to work on the software.

I reminder taking a security-oriented class ages ago and hacking on an operating system that was already dead as a trilobite, and we were all smart enough to realize this was not a triumph we’d be bragging about to our future children (or recruiters). Bleh.

So that already suggests a fantastic way to make some progress.

I think Tanenbaum had a unique vision at the time, but he went about it in the most ham handed manner possible and if not for VU Minix wouldn't even be remembered today. Linus had a huge advantage: he didn't have a lifestyle to support just yet.
