I bought my first PC in 2000, with Windows ME installed, it was/is a Celeron 700 Coppermine CPU in an eTower 700. These desktops offered DVD ROM and CD RW drives when they were very new features. I paid over $600 at the time (midwest USA). I was able to find the 950 chips when I found a Tualatin I bought did not work. The adapters are still rare, but finding out about the different 370 sockets was trial and error for me!
