What you want is probably hard to get. In case you might be satisfied with another vintage quality keyboard, check this site:
http://www.clickykeyboards.com/index.cfm/fa/items.main/parentcat/11298/subcatid/0/id/131781
The supplier sells original IBM model M keyboards. I do use one of these battleships in the lab, still (same league of weight and durability as our beloved Nimitz). Recommended for machines with a PS/2 port, but the clicky mechanism is pretty loud.
If you could do some programming for your target machine, you might attach the Apple ADB keyboard via network. To get the direction have some inspiration at the "excess keyboard remover" page: http://www.dashpc.com/osx/
Another similar software for the Macintosh is "Remote Mouse And Keys", successfully tested with Mac OS 8.1.
The page http://www.macwindows.com/keyboard.html#Applekeyboards is about connecting Apple keyboards to Windows computers directly.
If you might look for a new keyboard once, be sure to have a look at the Matias keyboard with original Alps keyswitches (the same, as in the old Apple Extended Keyboard) and a very advanced controller ( http://matias.ca/tactilepro2/index.php ). This also might give an ultra-deluxe solution for your actual need, in combination with an USB Female to PS/2 Male Adapter Converter for Keyboards (check recommendations for this application on the IBM-M-page mentioned above.
Btw: Has anyone tested an ADB-keyboard with a Griffin iMate connected to an USB-PS/2 adaptor ?
