Just out of curiosity, do you really know of anyone who is running a VAX-VMS system at present? My recollection of VAX minicomputers and VaxStations is that they would be considerably less powerful, have much less memory and possibly less disk space than a $250 netbook. The first VAX at our university, a VAX-11/780, was allegedly a "1 MIPS" machine but it was pretty difficult to get it to do a million of any instruction in one second. I eventually succeeded because it had a special instruction for decrement and branch on zero so if you loaded a register with 100000 and put it in a tight loop of that one instruction, it was able to count from 100000 down to zero within a second. When I bought the second Vax on the campus, a less powerful Vax-11/750, I was considered extravagant because I equipped it with a *second* megabyte of memory (at a cost of about $9000). I recently bought an Intel Atom and Nvidia ION based "nettop" computer for $330. That computer has a dual-core 1.6 GHz processor, plus 2GB of memory and 160 GB SATA hard drive. I expect the electricity and air conditioning bill for running a VAX would probably hit $300 after a few months, and that isn't even counting the cost of buying it and paying for (probably very old) operators to take care of it. And for that you would get a computer that is less than 1/100th as powerful as the micro desktop. Why would anyone do that? ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
