Don't have a cow, man! But seriously, after looking in the Xinu book, I see a couple of items by you are in the bibliography [A. Tanenbaum (sp? sorry but I don't have it with me at the moment)]. Sorry for the confusion. The grandiose AT&T logo appears on the inside cover of Xinu, and possibly ??? Minix? Does AT&T have a deal with Prentice-Hall, is it due to the basis of Minix on AT&T source code (naw, that would require a source license, right?), some AT&T control over Unix clones (I think that if you use you're own source code you're free from this automatically, right?) or just some other reason (perhaps I'm just plain wrong). Anyways, I would appreciate anyone who could give me more information as to the status of Xinu and any other OS code. (It doesn't have to be for Unix type, just anything that multi-tasks) Thanks all, I would appreciate it. Oh, and how much is Minix again for the Amiga, and how buggy are those disks? | Michael Griffith | If I had an opinion it certainly | | griffith@eecs.ee.pdx.edu | wouldn't be the same one as | | ...!tektronix!psueea!eecs!griffith | Portland State University anyways. |

Does AT&T have a deal >with Prentice-Hall [?] I don't have a copy of the Xinu book, but I can assure you that there is no AT&T logo in the MINIX book. I am virtually certain that Xinu does not contain a line of AT&T code, but you would have to ask Doug Comer to be 100% sure, as I am only 99.99999999% sure. The only connection betwen AT&T and PH is that when AT&T wanted to publish the system V manuals, they decided that they were really a phone company and not a book publisher. Thus they went shopping for a publisher, and chose PH. Given that PH is far and away the biggest computer science book publisher, this decision was undoubtedly made for business reasons, and has nothing to do with either Xinu or MINIX.

Minix? Does AT&T have a deal >>with Prentice-Hall [?] The AT&T "Death Star" does not appear in my 1985 purchase date Comer Volume 1, but does appear in Volume 2, "Internetworking with XINU". Douglas Comer's "Operating System Design: The XINU Approach" apparently did get some support from AT&T. Comer's affiliation on the title page is listed as "Bell Laboratories". The book was typeset at Bell Laboratories, and Comer's introduction concludes with the thanks: Finally, I am indebted to Purdue University and Bell Laboratories for support of the project, and to Bell Laboratories for the excellent typesetting facilities that made this book possible (nowhere near as fun as Andy's comments about computer games, mice and kids). As for Prentice-Hall, the book is listed as "PRENTICE-HALL SOFTWARE SERIES" Brian W. Kernighan, advisor. To digress even further into publishing, what are the numbers on the credits page for? Printing numbers, I assume? Enough of a plug for XINU :-) Now back to our regularly scheduled discussion of PDP/11 memory management. -- Glen Overby <overby@plains.nodak.edu> uunet!plains!overby (UUCP) overby@plains (Bitnet)

Yes. The line: 10 9 8 7 6 5 4 3 2 1 (ignition) tells which printing it is. On each new printing, they put some snopake-type stuff on the negatives to erase the rightmost number.
