ABSTRACT:
A desk-top electronic computer with MOS circuit logic comprising an input device, an output device and a logic unit adapted to carry out the various operations of the computer. The logic unit is disposed on at least two MOS circuit chips synchronized by a main oscillator. Each MOS chip is provided with a corresponding timing circuit adapted to generate mutually coordinated timing signals. The logic unit includes a read only memory or ROM for storing the microinstructions commanding the various functions, a computing unit and a control unit adapted to permit the selection of the microinstructions from the ROM by addressed access for the purpose of supplying a sequence of microinstructions to the computing unit, access of the address and output of the microinstructions taking place through a single connection between the ROM and the control unit.
