Looking back a little earlier in the history of Unix, we see that early versions ran on 16-bit architectures. Does anyone out there remember Version 6 on the pdp11. It most certainly did not share the address space (all 64k of it) between user and kernel. Are you trying to say that what Dennis and Ken wrote is not "Unix"? -Tony __________________________________________________ Do You Yahoo!? Yahoo!
