Please post a message if someone runs Xinu, I am sure others on the net would be interested.

Is a version of Xinu available for the Macintosh? If so... What hardware is required? How can it be obtained? How much does it cost? What book does it correspond to? Is there anything else one should know about it? Thanks for the info. -- Norman Graham Oklahoma State University Internet: norman@a.cs.okstate.edu Computing and Information Sciences UUCP: {cbosgd, ihnp4, 219 Mathematical Sciences Building rutgers}!okstate!norman Stillwater, OK 74078-0599

A version of Xinu for the Macintosh is available. It runs on Macintosh 512K, Macintosh Plus, and Macintosh II (we do not have a Mac SE to test it on). If an AppleTalk network is connected, Xinu will send and receive UDP packets, including rwho packets. If a time server is available, Xinu will set its clock from the time server, and, if a name server is available, it will get its host name. If the AppleTalk network has a Kinetics FastPath gateway to an Ethernet with the Xinu file server (which runs on UNIX), it can read and write files over the network. Xinu is compiled with the Aztec C compiler, version 3.5A. Compiling it requires about 2.5 Mbytes of disk space plus whatever the C compiler takes up. Hence, a Macintosh that compiles Xinu needs either a hard disk or access to a file server. There are software packages available that share a hard disk on a Macintosh over an AppleTalk network or share UNIX file space among Macintoshes. Macintosh Xinu is a port of version 7 (book 2) Xinu. It does not have a tty driver or disk driver. Instead, it maintains text window devices with I/O operations similar to those of the tty driver. Instead of handling hardware interrupts, Macintosh Xinu responds to events supplied by the Macintosh operating system, such as key presses and presses of the mouse button. Since AppleTalk does not have ARP, the ARP and RARP code has been replaced with code that uses Apple's Name Binding Protocol (NBP) to get IP-to-AppleTalk address bindings. In addition, Macintosh Xinu contains features that are not in the book version of Xinu. There are new devices called STDIN, STDOUT, and STDERR that are bound to a different real device for each process; these are used for UNIX-like standard I/O, and their bindings can be changed dynamically for I/O redirection, e.g., to a file or window. There is a device that maintains a per-process default prefix, which can be printed and changed, similar to the UNIX notion of current working directory. To order Macintosh Xinu, send mail to Xinu Librarian Computer Science Dept. Purdue University West Lafayette IN 47907 or send electronic mail to xinu-librarian@purdue.edu. The cost is $200, payable to Steven Munson. The Xinu source comes on two Macintosh 800K diskettes, and the Kinetics gateway software and Xinu remote file server come on a 9-track tar format tape. Note: There are new features since the distributed version was delivered, such as being able to boot when there is no Kinetics gateway and persistent text windows, which do not disappear when they are closed. If you want the latest version, send us your original Xinu distribution disks, and we will update them. Steve Munson sbm@Purdue.EDU sbm@Purdue.CSNET ----------
