[net.micro.68k] OS-9 vs. UNIX vs. homoousianism vs. heteroousianism

So can System III/System V named pipes, although it's not clear that the way
they're implemented in S3/S5 is the "right" way (something more like what it
sounds like Version 8 has might be better).

This is, at times, an interesting debate (and, at times, a religious
argument), but it's not clear what it has to do with 68000s.  (None of the
OS-9 concepts described here have much to do with the 68000 family
architecture, so nothing prevents them from being implemented on
non-68000-family machines.)

Certain aspects of OS-9 do require a minimum level of "robustness" provided
by the host architecture.  Many of the older MPU designs have serious
deficiencies that would seriously impair the resulting OS-9 implementation,
(e.g., 6502, 8086).

On the other hand, some architectures would be excellent hosts for OS-9 such
as the 32000 series or (yipes) the VAX.
