| Abstract: | In this paper the train of thought of the decipher read～out of a customer inside the single computer,the hardware block diagram,the maitining and the measures to raise reading raare intraduced. The plan is also suitable other analogous single—chip computers produc by Motorola Company. The solution of the question of the decipher read～out is quite crux to degist and use the electronic equipm which are imported from overseas and dominated by this kind of single—chip computers. |
