The sad reality is that MS has forced many to switch to newer OS’s. This was and is accomplished by them not providing support after a date certain. I am sure ALL are aware that XP goes on the short list in 2009. What ashame that they have forced computer owners and builders to upgrade equipment too. I for one have kept several 98SE/ME machines running because software written for that OS will not run properly on an XP machine. Now we have Vista-which is a terrible joke and intrusion on those of us who come from the days of the Commodore PET-can they get it right? Maybe in time, but the damage is done for those with software that won’t run right on it-upgrade and make the software houses rich-EEK.
To answer the OP’s question about buying 98SE/ME, I still have my set of discs and manuals. E-mail or PM me if you cannot find it. Definitely-DO NOT download as the License will not be valid. You will also need a bootable startup disc, which I have.
Good luck
