I started reading through Unit 1 of M362 the other day and felt immediately at home (and Unit 2 to boot). All those years as a Systems Programmer on IBM boxes and reading through much of the assembly source code of the Operating System (VM/SP, VM/ESA) means that I am on home ground when it comes to processes, context switching, interrupt handlers, various process states, user mode and supervisor mode, the fetch-execute cycle, and loads more. I know the course is going to move away from these topics eventually, but right now it feels good.
