Problems solved by technology

Because the debugging software on the experimental computer and personal computer is used to debug the experimental computer through RS232 communication, it is impossible to control the CPU in the experimental device for half a clock pulse and 1 clock pulse
Especially with the fixed monitoring program, the instruction set and system structure cannot be changed, so it is not conducive to the creativity of students
