Yes, it is one of the best sites still online. Unfortunately almost all of his external links are dead.
Here's an example. Where am I going to find a pinout for the video card in my DN4500? Apparently this is the video connector and the original cable is 3x BNC connectors for RGB out (sync on red). I need to make an adapter for this connector to VGA and use an old school multisync monitor that accepts sync on red.
I probably won't damage a monitor by trying all combinations of the 3, but I'd rather not do that.
