实现原理是由8279的8*2键盘控制373扩展输出口，由一位片选信号线连接的8088CPU的一个地址上，8279的每一个键值控制8088里面的每一套方案，由8088控制373扩展口输出给单色灯，实现节日灯的效果。-Principle is that by 8279 to achieve the 8* 2 keyboard to control the expansion of output 373, by a chip select signal lines connected to an address on 8088CPU, 8279 every 8088 key control inside each set of program control 373 by 8088 expansion of output to the monochrome lights, festive lights to achieve results.

（1） 有一个主持人控制开关和8路抢答按扭，当主持人允许抢答时才能进行抢答操作，并用一个数码管显示抢答选手的号码，同时其他选手不能再抢答。
（2）电路上要加个蜂鸣器的电路，当有选手抢答时蜂鸣器响一下。
（3）要有倒计时功能，开始抢答时开始倒20秒计时，用两个数码管显示，当有人抢答时停止倒计时。
2.2拓展部分
用按键可设置倒计时的时间，范围在5秒到30秒之间。-(1) has a host switch and 8-way control button to answer in, when the moderator allowed to be carried out to answer in time to answer in operation, and use an LED display to answer in the number of players, while other players can no longer answer in his place.
