I have seen a PC AT out run an 11/780. I don't mean to be a PC fanatic, but perhaps someone with access to a Symmetric could run a UNIX system benchmark suite and we could compare it to the PC AT and other machines in their price class. I have such a benchmark suite which I would gladly mail or post. This suite has been run on dozens of UNIX machines. I have trouble believing that a Symmetrics will out perform a 12Mhz PC AT substantially (more than say 20%) except in non-typical or VM benchmarks. I could believe that a PC AT would out perform a Symmetrics by as much as 30-50% on average while costing only $3000-4000. Let's run the benchmarks. BTW, the PC 386 machines will gain by 2-4X. > >Besides, who would ever accept a Xenix OS over 4.2BSD? 4.2BSD is MUCH nicer! I hear that someone is porting 4.3BSD to the PC AT and the cost will be dirt cheap. Cheers, Dan Ts'o Dept.
