The site is written in HTML 4.0 Transitional, with uppercase tags and even a bit of table layout at the end.

This is authentic, peak internet; note how fast it loads and how usable it is.

And MSHTML (Frontpage?) still wrote better webpages than webdevs do today.

Very authentic! It even has a closed forum that's pending an upgrade. To complete the experience they could've linked to the forum but left in the PHP error messages.
