A few days ago you posted an offer to reveal a site that had downloads of various versions of MS DOS and Windows. I have searched Google and Vivisimo (ever used that one - its good) and without going to all 60 or so links found I couldn't see an obvious match for your site (unless it was Downlod Center and the M$ police have been there and made them take off their MS DOSs). Could you please post the site you offered.
