To create an resetinput to the supervisory chip, its input must receive an active-low ground signal, requiring transistor Q1 to turn on.
为管理芯片产生复位输入,其输入必须接收低有效的地信号,需要晶体管q 1导通。

The purpose of this method is to store the currently displayed number into the accumulator, to store the specified operation as well, and to reset the display for input of the next operand.
In a case where a transformation begin, but aborts before completion, there are no facilities to guarantee that this condition will result in the reset of all input parameters to their previous state.
