8086/8088CPU的最大漠视和最小漠视
为了尽可能适应各种各样的工作场合，8086/8088CPU设置了两种工作漠视，即最大漠视和最小漠视。
所谓最小漠视，就是在系统中八有8086/8088一个微处理器。在这种系统中，所有的总线控制信号都直接由8086/8088CPU产生，因此，系统的总线控制电路被减到最少。这些特征就是最小漠视名称的由来。
最大漠视是相对最小漠视而言的。最大漠视用在中等规模的或者大型的8086/8088系统中。在最大漠视中，总是包含有两个或多个微处理器，其中一个主处理器就是8086/8088，其他的处理器称为协处理器，它们是协助主处理器工作的。

A

Three lawyers and three engineers are traveling by train to a conference. At the station, the three lawyers each buy tickets and watch as the three engineers buy only a single ticket.

"How are three people going to travel on only one ticket?" asked one of the three lawyers.

"Watch and you'll see," answers one of the engineers.

They all board the train. The lawyers take their seats, but all three engineers cram into a restroom and close the door behind them. Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, "Ticket, please" The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on. The lawyers saw this and agreed it was quite a clever idea.

So after the conference, the lawyers decide to copy the engineers on the return trip and save some money. When they get to the station, they buy a single ticket for the return trip. To their astonishment, the engineers don't buy a ticket at all.

"How are you going to travel without a ticket," asks one perplexed lawyer.

"Watch and you'll see," says one of the engineers.

When they board the train the three lawyers cram into a restroom and the three engineers cram into another one nearby. The train departs. Shortly afterward, one of the engineers leaves his restroom and walks over to the restroom where the lawyers are hiding .He knocks on the door and says, "Ticket, please." By copying the engineers, one lawyer put out a single arm with a ticket in his hand. The engineer came back to his restroom with the ticket. Then the conductor was coming this way...
