I know of at least the following additional assembly language operating systems that have sources, mostly on Bitsavers: 1. OS/8 - PDP-8 assembly language 2. XVM/DOS-15 - PDP-15 assembly language 3. CAPS-11 - PDP-11 assembly language 4. TSS/8 - PDP-8 assembly language 5. ADSS-9/15 - PDP-9/15

Is there a list of OS that have sufficient sources to rebuild it?Would be intresting to those who want to play.research OS designs.I suspect a lot of the old OS have lost their source code. --___ Simh mailing list Simh@trailing-edge.com

You might think that the Tanenbaum book would be narrowly focused on Minix. It isn't -- it covers operating system concepts in general. I recommend the book more than the OS. Minix is written to be an understandable classroom example. It does things that a serious OS probably would optimize

2016-10-23 Thread Dave Wade
Ray, I really suggest that you look at the Tanenbaum book. It goes into each component of an operating system and explains the structures that it uses and how the parts fit together. Looking at the code often does not explain this. Even were there are comments the usually don’t explain how
