- But that's not enough to write your own OS for, say, a Sun-4m machine.
- There's plenty of hardware that the OS has to tweak that's not specified
- by the Mbus or SBus (yes, that really *is* how they're capitalized, at
- least according to the specs I have; no, I don't know why the "b" in
- "bus" is capitalized differently) specifications.

- Well, the folks at the University of Utah *have* done a BSD port to
- various HP's; however, I think that, at least at one point, the port
- required that they lift some HP-UX code, and you needed a source license
- to get the source to their port.

- I.e., to fit Geoff's definition of "open", it's *not* enough just to
- have an "open" peripheral bus.
