Lines: 12 >1 VAX 11/750 = 1 MIP. ?? As far as I know, the Standard MIP is a 780. However it's probably better to ask people to say exactly what they are comparing with, i.e. what machine, OS, and compiler. Recently I've started to see "Ultrix MIP's" quoted. Apparently this is a comparison with a VAX 780 running Ultrix. The theory is that it's only fair that a Unix system should compare against DEC's Unix. However if this is an excuse to use the old f77 instead of DEC Fortran, the result is being seriously biased. And even then, there's going to be a range, depending upon the application. E.g. Sun rated their 4/280 at 10 VAX MIP's. I think most people now believe that 8 is more like it, but more like 5 for Fortran, and probably considerably more than 10 for Lisp.
