Probably the AT101W. The only similar-looking Dell keyboards are the rubber dome Quietkeys have much less bezel above the F-keys.
Cool, that gives me hope. He emailed me back from work saying he'd look for the model # when he got home from work. He's got this keyboard, an old 15" CRT, and a RF modulator for sale for $25 as a package. Don't need the other stuff, so I might just offer him $10 for the keyboard. That seems fair to me, especially since it's new. Well, maybe not new, but unused.
Edit:
Just got word. It is an AT-101W. He said the cord has never even been unwrapped. Think I'll pick it up. Now I need to find a black one, switch the WASD and ESC keys, and sell them as high end mechanical gaming keyboards.
