okay let's do some industrial archeology 好吧，让我们做一些工业考古，这是一台pdp-11坚果小型计算机
okay let's do some industrial archeology 电路板，所以在微型计算机服务器mini出现之前就是这样
okay let's do some industrial archeology this is a pdp-11 nuts mini-computer 是该组件上非常漂亮的标志处理器里脊，看起来是两个相同的
this is a pdp-11 nuts mini-computer 芯片，它们是一个串行端口，你是艺术，如果放大到其中一个
this is a pdp-11 nuts mini-computer circuit board so before there were micro 您可以看到它是由一家名为General Instruments的公司制造的
circuit board so before there were micro 消失的公司现在不确定谁拥有他们的资产，这是明显的8 y 5 10 13 a
circuit board so before there were micro computers servers minis and this is it 这是一架建于1980年的飞机，但随着我们要迅速找出
computers servers minis and this is it 设计出处比起我要早很多
computers servers minis and this is it was a pretty iconic processor loin on 打包，然后我们将实际的照片保留下来，
was a pretty iconic processor loin on 一个中等规模的集成部件的典型代表，这个已有50年历史了
was a pretty iconic processor loin on this assembly are two identical-looking 显然，我们得到的键合线从边缘出来，
this assembly are two identical-looking 休伊特中心部分当然有丰富的霍尔特旧逻辑，让我们放大一下
this assembly are two identical-looking chips they are a serial ports are you 芯片通用仪器GI当然是1971年
chips they are a serial ports are you 这当然使它在50岁以下就有点老了
chips they are a serial ports are you arts and if it is zoom into one of them 芯片，如果我们看看其中一个I / O垫并实际上将其分开
arts and if it is zoom into one of them 在你身上-我不踩，所以让我看看我让他们突出显示这一个
arts and if it is zoom into one of them you can see that it's made by a company 这儿还有黏合垫，这小块狗基本上是金
you can see that it's made by a company 一个很好地和干净地分开，你可以看到它的典型
you can see that it's made by a company called general instruments long since 一种结构，现在让我在这里查看原理图，这样我们就可以开始
called general instruments long since 另一个是顶部，基本上是用于钳位的ESD保护二极管
called general instruments long since gone company not sure who owns their 它们可以防止二极管，如果您在CMOS中存在过压，则不需要
gone company not sure who owns their 打电话来闩锁，您可以看到这种蛇形发生的情况，这非常
gone company not sure who owns their assets now it's a marked 8 y 5 10 13 a 在CMOS电路设计中非常普遍，基本上我们有两个
assets now it's a marked 8 y 5 10 13 a 二极管在此一侧上，在此一侧上，以及其原因
assets now it's a marked 8 y 5 10 13 a and this one was built in 1980 but as 蛇形基本上是二极管功能上真正存在的
and this one was built in 1980 but as 外围，因此通过延长线和
and this one was built in 1980 but as we're going to quickly find out the 从本质上讲，您可以创建一个日记，该日记将增加当前的容量
we're going to quickly find out the 这种特殊情况的输出焊盘连接在顶部金属上，
we're going to quickly find out the design provenance is a quite a bit 这里的结构和这里发生的相同的事情，但是我们现在有一个
design provenance is a quite a bit 顶部一对晶体管的结构稍微复杂一些
design provenance is a quite a bit earlier than that let's I take the 这是底部之一，这是内收希望通过的是驱动程序
earlier than that let's I take the 这就是晶体管II的原因，它非常大，基本上可以让您
earlier than that let's I take the package off and then we got the actual 驱使信号进入雪的边缘可能会死亡，然后偏离航向
package off and then we got the actual 包，最终可以将其固定在某个东西上，比如说我拿了一个
package off and then we got the actual on a hold I photograph and a very 看框图关于这个时代的集成电路的好处是
on a hold I photograph and a very 他们实际上有相当广泛的框图，基本上是分开的
on a hold I photograph and a very typical of a medium scale integrated 分为两个功能：接收器和发送器芯片，接收器数据
typical of a medium scale integrated 核心在这里，您可以看到向外传播，这意味着被驱动进入
typical of a medium scale integrated part this one is a 50 years old so 收到的处理器部分基本上已经注册了加热器，因此
part this one is a 50 years old so 将会有八位长的数据总线，并且这里将有移位寄存器
part this one is a 50 years old so obviously we got the bond wires are 他们说的东西很长，所以要输入数据，然后有一些逻辑
obviously we got the bond wires are 基本上检查启动是一个串行协议，您可能将其称为rs-232或
obviously we got the bond wires are coming out on the edges and a sort of a 串行端口和较旧的个人计算机基本上是一个协议
coming out on the edges and a sort of a 哪一个进行了奇偶校验，然后开始进行校验
coming out on the edges and a sort of a center part Hewitt rich of course Holt 生成器向下移动，但基本上所有这些逻辑都将其移位
center part Hewitt rich of course Holt 进入这里，他们走了过来，在这里登记了门铃错误
center part Hewitt rich of course Holt old logic let's zoom into the mark on 本质上对处理器说是可读的，然后是
old logic let's zoom into the mark on 它放在这里，处理器必须读出来，这里没有深度
old logic let's zoom into the mark on the chip general instruments GI of 一个字节，因此处理器必须相对较快，然后
the chip general instruments GI of 可以在发送端阅读它，我们知道这是完全一样的，但是
the chip general instruments GI of course and there's that marking a 1971 而不是向外发送数据，而是由处理器向内驱动
course and there's that marking a 1971 它被保存在一个寄存器中，然后被转移到一个发送寄存器中
course and there's that marking a 1971 which of course puts it just a little 开始向外移动，然后向上移动，我想我
which of course puts it just a little 倒退了，因为它向外移动，变成了一种好
which of course puts it just a little bit under 50 years old so this is an old 串行端口上的连接基本上是我认为可以重新填充的过程
bit under 50 years old so this is an old 这个缓冲区并填满它当然是一样的东西
bit under 50 years old so this is an old chip indeed if we take a look at one of 要做到这一点，您现在知道在这些芯片时代相对较快地上法庭
chip indeed if we take a look at one of 奥黛丽的最大功率为30千瓦，传统上为VT 52
chip indeed if we take a look at one of the i/o pads and actually part me this 终端，它很常见，可以连接到您当然知道的pdp-11计算机
the i/o pads and actually part me this 具有微秒的yo V，可以将D移出，所以这很合理
the i/o pads and actually part me this at you - I don't pad so let's see let me 到时移器的方式，所以在这里我们在接收器中形成了裸片
at you - I don't pad so let's see let me 底部和发射器顶部，因为通常发射器是晶体管
at you - I don't pad so let's see let me just I get them highlighted this one 基本上只在术语上是在接收器上看到的
just I get them highlighted this one 当然是本土主义者的收发器，它们都将要使用
just I get them highlighted this one here still has the bond pad this little 垫的相关部分和其他部分，然后在此处AB，您会看到接收器和
here still has the bond pad this little 当然，现在我们不能整理一点逻辑，例如，这应该是
here still has the bond pad this little block of dog is basically gold on this 关于触发器的价值，因为这是因为他们吃了，但是
block of dog is basically gold on this 在这里缓冲看起来像是吃了这些食物再加上它们以求平价，
block of dog is basically gold on this one here it's nicely and cleanly 状态位，然后是顶部的移位寄存器
one here it's nicely and cleanly 在这里，我将放大典型的翻牌，现在您可以看到实际上这是一个
one here it's nicely and cleanly separated and you can see it typical of 非常典型，看起来像是手工铺好，因为它很亲切
separated and you can see it typical of 在这里，您手工制作的各种东西都非常特别地做了
separated and you can see it typical of a structure now let me just go to a 未来至少十年内
a structure now let me just go to a 这是从芯片设计中获得的，但是这次当然可以看到它很不错而且很常规
a structure now let me just go to a schematic here so we can start down one 所以所有这一切都可能是根据其放置位置进行了计算机化处理
schematic here so we can start down one 在那个女人身上做的，实际上是法院被一个
schematic here so we can start down one and the other so the top basically our 计算机辅助设计系统再次产生实际的最终艺术品胶片
and the other so the top basically our 那是白色的，如果回到这条规则，一切都会很好，也很奇怪
and the other so the top basically our ESD protection diodes for clamping 耳环开始看到真正弯曲的线条，但到今年，我认为我们已经
