"Brian Benchoff at Hackaday has an ambitious new project: a homebrew computer based not on a classic 8-bit processor like the Z80 or 6502, but on the 16-bit Motorola 68000. It's a backplane-based machine with wire-wrapped connections planned. His first summary post is here. Blinkenlights are planned."

[ED Note: With so much commercially available hardware getting more and more locked down, projects like this are a good reminder of what is possible for a dedicated enthusiast.]

    Yea, but that's not really Unix. And I'm saying that as someone who believes Linux is Unix.
    Basically you're left without memory protection; which doesn't really make something non-Linux by itself.
    However you are unable to dynamically grow the size of heap or stack for processes. So like Minix you either allocate a standard stack size for everything or you specify a specific stack individually for each process. All memory is shared, everyone presumably allocates from the same heap, etc.

    True. But given the limitations of the 68000, I would rather run something Linux-like than System 7-like. If you can't have memory protection, you might as well have preemptive multitasking!
