The channel 0 of ADC0809 is used to connect to the DC voltage of 0-5V, to adjust the analog voltage value with WR potentiometer. The end of A/D conversion ends EOC to the IR5 of main 8259A, collecting 100 data and storing it in memory, and collecting the 16 binary data displayed on the digital tube. Please adjust the voltage value of 0-5V times (W1, A/D rotating knob) acquisition, change was observed in memory data.
