Howdy, I recently had a chance to browse through some poor condition Apple Design Keyboards, and the country of origin of one caught my eye - it clearly says "Assembled in USA" on the bottom, so I took it home:
It's in appalling condition, very yellow and dirty.
On closer inspection, it does not appear to exactly match any of the known variants on Deskthority. This particular keyboard is clearly alps, as it has alps compatible keycaps and what seems to be alps dome with slider switches:
Note the backing panel is cream plastic, the other examples I can find are dark grey or black. The backing panel is also
not curved.
The electronics are apparently true-blue alps:
The date stamp on the top housing is hard to decipher:
I'm guessing it says 28th of June, 1993?. It has poor quality abs keycaps (they are very yellow), and what appears to be pad-printing, and the caps lock is stepped, consistent with alps-produced versions:
Lastly, here is the FCC/other info:
Anyone found another USA produced Apple Design Keyboard? Does this suggest that Alps briefly produced the ADK in the USA before moving to Mexico/Czech factories?
