The American multinational telecommunication giants, Motorola was founded in the year 1928, initially under the label Galvin Manufacturing Corporation. Their first product was a battery eliminator, launched in 1928. After an array of products that continued till early 1980’s, Motorola launched their first training computer, the WDR-1-Bit Computer. Also one of the rarest computers in the world, this machine worked under Motorola’s MC14500 processor. This machine was bought and sold in Germany by DATANorf Hard and Software groups. The WDR-1-Bit originally is not a microcomputer, but rather an Industrial Control Unit (ICU) that was designed to control industrial devices for successive binary information’s based on single bit offered. The computer or ICU includes a LED IO keyboard, a CPU board and a 512 byte RAM board, that can easily be operated using a 9V battery. Another interesting part was that the sound produced from the system was as a result of attached amplifier and loudspeaker.
