ADJUSTABLE_CLOCK_WITH_MEMORY_READY
Additional timing resistor is switched in or out of MC8602 pulse-width generator for phade-2 clock to provide memory-ready feature along with variable clock frequency for MC6800 microprocessor.Selection of timing resistors for phade 1 and phase 2permits generation of all combination of phase 1,phase 2,and stretched phase 2 pulse widths. All transistors are MPQ6842. - Microprocess Applications Manual (Motorola Series in Soil-State Electronics), McGraw-Hill,NEW York,NY,1978,P 4-61.
