Not really, total system cost for a headless router box is adds only 1.44floppy $36, 500MB disk $248, NCR SCSI $72, case/power $70 or $426.00, for a total of $706 vs $1146. 62% is a hit any way you count the beans :-) > > >of money.

It would always be possible to build better routers using dedicated and carefull chossen hardware and custom software than any GP and OS based router. I don't think there is anyone who will argue with that. I was just trying to point out that David's statement about 486 vs Pentium being a ``fairly small'' amount of money these days is simple not true. I think I have good ground to stand on as a person who is making there very living selling PC hardware and deal with the price/performance trade off issue almost every day of the week. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
