It could happen. Remember the PDP-11s? 512k RAM and it supported 16 or more users... (this isn't quite a fair comparison...) : Similarly, when the "typical" usage of a telephone switch might be 3 to 5 : percent, it would be economically ridiculous to design the switch to run : at 100% capacity 100% of the time. This would surely result in no one : being able to afford telephone service! This running of machines at less than 100% percent is a recent thing. The old mainframes were run as close to 100% as possible. They could not afford to waste the cpu cycles. The advent of cheap cpu time changed all this. When this same thing happens to the phone company, you have to wait a bit for a dialtone. The PBX on campus does this right around phone in class registration. :) As someone else said FR is the way to go... -- --------------------------------------------------------------------- Matthew N.
