用8088CPU构建一个微机应用系统，8255A、8×2键盘、6位七段数码管（共阴）； 6位LED数码管可显示时、分、秒，并按正常时间显示方法工作；0~9为数字键，A~F为功能键。刚做的课设，有报告，有源程序，有硬件结构图-Used to build a computer 8088CPU applications, 8255A, 8 × 2 keyboard, digital tube paragraph 6 (a total of Yam)　6 LED digital tube displays hours, minutes and seconds, and the normal time display method of work　0 ~ 9 for the number keys, A ~ F for the function keys. Just make the class-based, it has been reported, has the source code, has the hardware structure diagram
