More on this type of keyboard...
The IBM Portable Personal Computer Keyboard was a lightened and entirely plastic-cased version of the Model F/XT for the IBM 5155 Portable Personal Computer. The internal assembly is unchanged, with the cable connector being the only technical difference between them (although the protocol was also unchanged). A notable unique feature of this keyboard is the large hole in the case designed to help hide excess cable length in when the keyboard is folded down from the computer or hide the cable completely when folding up.
