i'm using an ibm thinkpad 600e for my homebuilt telescope. i have to use this because the software uses dos and only dos plus nothing higher than windows 98. i found a used ibm on ebay with a few software problems so i installed a unused version of 98. my question is, is microsoft still registering windows 98 and do i need to register it with them. i don't have the internet on this computer so if i need to register it how do i do it? can anyone help me with this?
