Is it possible for me to easily obtain the CPU ID on my Decstation 3100? The software salesman plans to use it to restrict distribution of the program. Thank you, Jay Sparks

In many (most?) cases, the hardware ethernet address is in a PROM that is socketed for this very reason. When a board breaks, take the socket out and plug it into the replacement - it'll be the same I.D., ergo no broken software. Of course, in the unlikely even that it is the PROM that breaks, you're out of luck. *UNIX is a registered trademark of AT&T in the U.S. and other countries. -- --------------------------------------------------------------------- Richard Wood Corporate Worksystems Team Digital Equipment Corp. ======================================================================== [Not an official spokesman yet...]
