I didn't look too closely at that other site to see what they were trying to do, but I assume all they wanted to do was wire all the same lines to each other (data on ps/2 to data on AT connector, clock to clock, power to power shield to shield etc..., where ps/2 is 6 pin mini din and AT is 5 pin DIN).
I do have a link to a site that has proper pinouts, shown for both types of connectors, and shown from both the cable perspective, and the socket perspective, so you can correctly map it from any direction to any direction. I used these pinouts when I was experimenting with my custom keyboard encoder for both types of keyboard cables, so I know the pinouts are correct.
So I'd feel 100% at ease with using this site's pinouts and just wiring the similar pins to each other on each cable and then, whether or not it works is another issue (it won't FRY anything but it may not work, I couldn't get my AT keyboard to work on my PS/2 keyboard port of my particular motherboard for some reason, but I know both keyboards I have use different timing so maybe my motherboard is just picky)...
So feel free and comfortable use THIS link:
