According to it sounds as though it should be compatable.

Is the disk used to upgrade 95 to ME also for upgrading 98 to ME. If not, that may be a problem.

Also, buying a used computer can be kind of like buying used auto parts. You may not know just what you have until you try to use it. May be better off just reformatting and installing a new operating system on it.

BTW, if you are attempting to use the same upgrade disk on multiple computers at the same time with out licensing for such, you may be risking potential legal problems.

Hope this helps.
