A computer interface console includes a cathode ray tube display, an operators keyboard, and an engineers keyboard. The engineers keyboard is so mounted that it may be moved to a position in front of the console in substantial alignment with the cathode ray tube and the operators keyboard when it is desired to make changes in the computer data base. At other times, the engineers keyboard is moved to a retracted position below the work space of the console, under the operators keyboard. In that retracted position, the work space is clear and uncluttered by the engineers keyboard. Additionally, with the engineers keyboard in the retracted position, it is unobstrusive and unavailable to unauthorized operators. Thus the probability of inadvertent or unauthorized manipulation of the engineers keyboard is greatly reduced. |
