I have a hole in my desk with a grommet in it right above my mouse mat in the center of my desk. This lets me run the cables for my keyboard and trackball under my desk and not have cables snaking across my desk.
Since you can replace the Apple cable with a standard s-video cable, I went that route. My son found me a black S-video cable at a local thrift store for $1.00 and I had been using that. But with the cable running out of the side of the keyboard, along the back of the keyboard and into the hole, it was putting more strain on the cable than I liked.
A few days ago I found these online:

An angled s-video cable. Exactly what I was looking for.
And, as you can probably guess, the slide out foot on this keyboard no longer slides out. That's why you see the rubber feet on the keyboard. I have another AEK II where the slide works. But the foot really only offers support at the center of the keyboard. If I slide the foot out and press on the upper right and upper left corners, the keyboard pushes down a little. Since I am a pretty heavy typist this causes the keyboard to wobble when I hit some keys on the left and right side of the keyboard.
So my questions:
1. How hard is it to fix the slide out foot on these keyboards?
2. Should the keyboard foot provide support from heavy-handed typing across the entire length of the keyboard or is common for the corners put give a little when you push on them?
