Abstract
A microprocessor controlled computer security system is disclosed that provides for controlled access to single or multiple components of a computer system. The security system includes a magnetic card reading and encoding device that reads component access and time allotment data from a magnetically encoded card. A microcontroller, which incorporates a microprocessor, processes the data read by the reading and encoding device and responsively issues enable or disable signals through a component interface circuit to the computer system component or components to be enabled or disabled. The components to be enabled may be the video display device, hard disk drive, or external central processing units of slave computers. The security system further includes audio and visual indicators that provide system and component status information. The magnetic card reading and encoding device is operable in a program mode, wherein the magnetic card is programmed with component access and time data, and a reading mode wherein the reading and encoding device reads and updates the access and time data on the card.
