Abstract
A restricted access computer system. The system comprises a general purpose computing platform and a control system comprising a control hardware device and a control software program. The control hardware device is connected to the computing platform and to an access-status device such as a coin hopper or the like. The control software program runs on the computing platform and, in a secure mode, replaces the graphical user interface portion of the operating system of the general purpose computing platform. The control hardware device and control software program interoperate to allow access to application software programs on the computing platform only when certain conditions are satisfied. The control hardware device resets the computing platform if the control software program fails to communicate therewith. The control hardware device also restricts operation of the user keyboard and display monitor to reduce the possibility of unauthorized use of the computer system.
