I’ve only read through a couple of the pages, and I found that there’s a lot there that doesn’t align with my memory of building things for the web at the time.
I’m not quite interested enough to dig through and find citations for most of it, but here’s one that stood out. The author claims this screenshot is from 1994. While the copyright date on the browser was 1994, the screenshot certainly isn’t that old. Those IE and Outlook express icons on the bottom are from quite a bit later than that.
Good catch, the OS is most certainly Windows 95 in that screenshot with IE 4.
It’s most likely Windows 2000, note the gradient of the Netscape Navigator title bar.
I remember Win2000 having higher fidelity with the icons, and I did a short research, but I shouldn’t have written “most certainly” I guess :)
