It's definitely an old one.

I had my problems here with it too.
The only way it works for me here is, that you have to press
the CMD+OPT+O+F while you press the Reset key on the box.
(Original apple ADB keyboard)
And here it only works with the CMD+OPT on the right side of the keyboard.

Please let somebody make a picture while you're trying to press all this 
buttons at the same time ;-)

Something went wrong there. I had this problem too, unpacking it on a PC 
with some tools, only had succes after finding the disk with the MacOS & 
the unpack program ...

But try the keyboard again,
That's the easiest choice at the moment.
