OCTAL_DISPLAY
Circuit provides display of 8-bitdata word in conventional octal form forconvenience in experimentation with microprocessors and small computers. Three-state counter built around synchronously operated JK flip-flops provides digit and data selection. The two or threq bits appropriate to each display are steered to 7-segment decoder by wired-AND gates and inverters. Oscillator multiplexing frequency is about 2 kHz.-R. D.
