In a previous position at the University of Washington, I was responsible for converting from AOS/VS 5.something to DG/UX 1.0 on a DG MV/10000. Of course, there were a lot of problems, but performance (when the machine was running :-) wasn't one of them. It took a few revisions of DG/UX to get the most serious problems resolved, but when I left the position we were at revision level 3.11 of DG/UX and the machine was working reasonably well. I would also point out that DG/UX is a great development (or at least testing) environment, if you are developing UNIX applications! Why is this? Well, you have a couple of things going for you: 1. You have a machine that is almost legend within the C / UNIX community. If you don't understand how to write clean C code, spend a few years on an MV, and you will soon learn to properly type your pointers, and you will become intimately familiar with the argument types of the various library routines! 2. You have an excellent C compiler. It's well documented, it works, and it has about every option you could imagine to help you debug bogus code. 3. I was excited about the new debugger in DG/UX 4.0, but never got to use it. It really looked like a great tool. I'd be interested in knowing how it worked out. > Also, and I realize this is not the best news group to handle >it, can someone comment on the AViiON, or compare it to VAX11/780 or >something else in the same range ? Comparing it to an 11/780 would be rather odd. Maybe you should compare it to something like a Sun Sparcstation or a DEC PMAX.
