Having worked for vendors before, and having been active in the workstation marketplace since Sun was in 2-digit serial numbers, and having been a software consumer for a hell of a lot longer than that, I feel that I can safely say that the stuff proporting to be an operating system on the 6000 is nothing I would be comfortable calling "beta", much less "pre-release" which implies damn near done. Hell, I wouldn't have shipped that stuff as "early alpha". > I would suggest that that be kept in mind.

Indeed I did; I also considered the meaning of "pre-release" in standard software-speak. But while I feel that the hardware is a good design, and a good value for the money, but that the software is a real crock. In a way, it's the worst of all possible worlds: the RT was so S L O W that you didn't notice that the software was crap; however, it's pretty hard to miss something like that on an alleged 27 MIP platform. Maybe if the CMU guys get Mach and X11R4 running on it.... > Followups, if any, should be directed to comp.unix.aix, please. Done. Stanley P.

Oh, sorry. I forgot we're not supposed to notice that putting features in a portable operating system is much harder than to hack things in to a particular machine. -- A.
