You don't have a real operating system without it. On the Mac we have a compelte verison 7 system that includes multiple process support, real-time clock, message passing, networking (including the remote file system client, ICMP and UDP echo processes), the syntactic namespace, support for Mac windows, a UNIX-like shell and a set of commands. On the PC, we have all of version 6 plus window support, MS-DOS interface (e.g., for the file system). No networking, yet. I have a couple of students working on that this summer (biggest problem: finding an Ethernet interface card that stands up to the load on our Dept. network). If you want to use the Mac version this fall, I'll give you a copy of the manuscript for the Mac version of the book. The PC edition is already out. Can you take a trip out here this summer to visit and see what we have running? Cheers, Doug
