Back in the 80's, AT&T started asserting copyrights on Unix v7, which
meant that professors stayed on Unix v6 for educational use (teaching
college courses in operating system design). The famous "Lions' Book"
started as a Samizdat* version of one professor's lecture notes:
Fast forward 30 years and Unix v6 is no longer a good teaching tool: it
targets a 16-bit PDP 11 and is written in pre-ANSI C (pre-K&R even). So
the MIT open courseware people decided to write a new one in C99
When you clone the git repo on that page and type "make", it builds a
filesystem image that boots to a shell prompt under qemu.
Now _my_ question is, what would it take to port this to j-core and boot
it on a MimasV2? (At which point you can have a _pair_ of courses: the
hardware side in VHDL and the software side in C. :)
* Useful word. The soviets had an oppressive totalitarian regime, we
have copyright law. Six of one...
