The machine in question is a DECstation 5000, upgrading to a 5000/260 by replacing the R3000 chip with the more powerful R4000 . With the new chip will the existing copy of Mathematica... 1. work at all ? 2. be correctly licensed ? 3. have to be reinstalled ? 4. if 2 or 3 will the same password be valid ? For support at wri.com : If the answer to any of the above is NO, will there be any cost involved with obtaining the appropriate upgrade, in order to return to a properly working Mathematica system? As the current kernel version is only 2.0, will such a cost be any more than the normal upgrade cost to version 2.2 ? Eagerly awaiting any replies, Ross Moore
