Teaching system using computors equipped with screens and connected in a closed loop with a teacher control station
First Claim
1. A teaching system comprising a plurality of computer stations serially connected in a closed loop circuit, one of said stations being a teacher control station and the remaining stations being student computer stations, at least said student computer stations each comprising a computer device having an associated video monitor connected thereto via an interface unit, said teacher control station having a controller device connected between any two interface units of said student computer stations to transmit an information network signal in said loop circuit to condition selected interface unit to place its associated computer station to a preselected mode, and a keyboard associated with said controller device for selecting said mode, visual indication means associated with said controller device to provide a visual indication at said control station of said selected mode, said interface unit having a plurality of electronic switch means to condition its associated computer station to a predetermined mode selected from either an individual mode, a source mode or a target mode, said predetermined mode switching one or more interface units where address codes stored therein match with said predetermined mode, each said interface unit being interconnected through said single main cable bridging said interface units for communication with designated interface units, said cable originating from an output of said teacher controller device and terminating at an input thereof.

Abstract
A teaching system comprising student and teacher computer stations which are serially connected in a closed loop circuit. Each student computer and the teacher station comprises a computer device having an associated video monitor connectable thereto via an interface unit. A teacher controller device is provided at the teacher control station and has an output connected to the interface units to transmit an information network signal thereto to condition the interface units to place its associated student computer station to a preselected mode. A keyboard is associated with the controller device at the teacher control station for selecting the mode. A visual display on the controller indicates the selected mode to the teacher.
