Juul, arnej@lise.unit.no It seems my message has stirred up quite a flamewar on gnu.misc.discuss, it seems tempers are really hot on the issue of apple here, both pro and against. Actually, if I may say so, some of the discussion seems a bit silly (speculating about my motives, whether my means are immoral, etc.) So to sum up some of my reasons for the question: The local computer pushers (sells Macs, IBM-PCs, etc) has currently a big campaign 'introducing Unix in Norway'. (This means introducing A/UX at the university, actually). They are promoting Macs with A/UX for a lot of reasons: It has the technologically best solutions, it works well in any environment, can communicate successfully with all types of machines, it is standards-compliant, etc, etc. This may of course be true, but I am always very doubtful about all such claims when I do not know the OS in question. The salesmen in question would certainly like to have everybody on the university swap their Unix machines with Macs running A/UX, as this would mean tremendous sales and profits for their company (There's at least 450 Unix machines here today). That's OK, too, that's their job. But I, personally, do NOT think I would like having only A/UX machines around. So I asked out for what the problems with these machines are. Because I plain refuse to believe that they are the answer to Man's problems. There's another side to this: I know a lot about some of the design flaws and traps with the OS's I've worked a lot with. (SunOS and Ultrix). This means I consider myself capable of judging these systems, their relative merits, and make suggestions as to what people should buy, what they can expect, etc. But I won't sit around with someone who's going to buy a machine and tell them of all the things that works well on the machines. If it works, it isn't extremely interesting. I posted first to gnu.misc.discuss, partly because I know there is strong anti-apple feelings here. On numerous suggestions, I have also posted to comp.os.aux. Neither gave me many answers (gnu.misc.discuss gave the most response), but I thank those who took their time to answer my questions without flaming. ...after this long and windy preamble, here's the summary at last. I hope those quoted do not mind, I have only edited out my own previous postings which were cited in all answers. Flames etc. have not been included here, nor answered. > Date: Thu, 24 Oct 91 13:08:47 PDT > From: paul@hal.com (Paul Sander) > To: arnej@lise.unit.no > Subject: Re: A/UX comments wanted > Organization: HaL Computer Systems > > Arne, > > I've been using A/UX for about 10 months now.

They all say the same: OUR unix is the best there is. I don't believe any of them.) The missing thing about the presentation was the usual fancy colourful diagrams showing how the Vendor's machine is at least twice as fast as any other vendor's, or at least has a price/performance twice as good as any other vendor. If I get any first-hand experience with A/UX, I may share my experiences with you all. :-) ----------- Arne H.
