User:Numeric
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.

Ultrabay Plus Device Carrier installed in a T23. This is a picture from the side, showing what the carrier looks like when closed.
