I have learned so much from ThinkWiki. Without ThinkWiki, I probably would never have learned of Ultrabay Plus Numeric Keypad. I searched the Web for more information about it, but could not find anything beyond the article here and IBM support pages. So I got one and took a few pictures of it. I release these pictures to the public domain.
