Well I said I would get back to you if SP1 was found to be anywhere on the web and it is, our friend Bink (the newsletter guy) has posted it on his fab site www.windowsxp.nu. The file weighs in at 11.6mb I cant tell you if its worth the download because as I type this my download is still going.
Its being hammered so be patient. If anyone can mirror it, please let me know or drop a comment.. cheers.
Download: Internet Explorer 6.0 SP1 (build 6.0.2813.3000) (scroll 3/4 of the way down)
