1. An interface circuit for use between a radio control transmitter equipped with encoded signal outputs and a computer data bus, said interface circuit comprising:
- a microprocessor including incoming circuit connections from said radio control transmitter encoded signal outputs;
a first latch including incoming circuit connections from said microprocessor;
a second latch including outgoing circuits to said microprocessor;
a bidirectional buffer including incoming circuit connections from said first latch and including outgoing circuit connections to said second latch, said bi-directional buffer further including bidirectional circuit connections to said computer data bus; and
a first one-way buffer including incoming circuit connections from said computer data bus and an outgoing circuit connection to said bidirectional buffer, said first one-way buffer operated in response to signals received from said computer via said data bus to control the direction of flow of information through said bidirectional buffer from said first latch to said computer data bus or in the alternative from said computer bus to said second latch.

Abstract
An interface circuit for use between a radio control transmitter equipped with joysticks and a standard data bus of a personal type computer. The interface circuitry includes a microcontroller operated as a reformatter for signals received from the remote control transmitter and a number of integrated circuit latch and buffer circuits connected between the output of the microcontroller and the data bus of a computer to convert the signals output from the microcontroller to the data bus on a direct basis.
