That diff is for 8 May 2001 but if you look to the left the "older" (previous) diff is dated 25 September 2011.
The diffs are going backwards! I was trying to find the very first diff for [[[[Sony]]]]. I would have to do some major clicking to even get back to May 8. I have Windows XP Pro, Google Chrome Version 46.0.2490.71 m, browser, and the Vector skin. Please advise. Cheers! ~~~~
