-2.1.1 Experimental computer peripheral needs: the experiment with the computer keyboard and printer two external devices. Peripherals and memory to operate a unified command, the program check the use of peripheral fat. 2.1.2 Experimental computing structure: a single-accumulator calculator and more general-purpose registers 2.1.3 Structure function and the use of experimental computer: keyboard input of the two to two decimal arithmetic, the output from the printer　to carry out keyboard input of the odd-numbered i (i = 1-255) and deposited back to beat out No. 100H in the beginning of the memory modules
