概要： 关于苹果第一代Macintosh的开发以及制造它的人的轶事: 创建第一个基于样条线的字体系统 , 基于样条线和抗锯齿字体的起源 Origins of Spline-Based and Anti-Aliased Fonts
In the spring of 1971, I took a break from high school and worked in the computer department at the National Institutes of Health in Maryland for two months, from April to May.
1971 年春天，我从高中休学，从 4 月到 5 月，在马里兰州国立卫生研究院的计算机部门工作了两个月。
I had to work on the PDP-6 and PDP-10 computers with a team of people, including Dr. Bob Sproull.
我必须与包括 Bob Sproull 博士在内的团队一起研究 PDP-6 和 PDP-10 计算机。
They used a special machine called a Calcomp Film Plotter. This machine drew on film using a tiny beam of electrons. This meant it could draw very detailed and clear pictures, making it good for publishing.
他们使用了一种称为 Calcomp 胶片绘图仪的特殊机器。这台机器使用微小的电子束在胶片上绘图。这意味着它可以绘制非常详细和清晰的图片，非常适合出版。
Bob asked me to find ways to make font sizes that can be zoomed in and out. He also wants to be able to change the shape of the font, like making it slanted or italic.
鲍勃让我想办法制作可以放大和缩小的字体大小。他还希望能够改变字体的形状，例如使其倾斜或斜体。
I spent about a week thinking about the problem and figured out the best way to solve it was to use a mix of straight lines and curvy lines. I also made a system to store font information. To show how it works, I did the letters “I” and “P” as examples.
我花了大约一周的时间思考这个问题，并找出解决该问题的最佳方法是混合使用直线和曲线。我还制作了一个存储字体信息的系统。为了展示它是如何工作的，我用字母“I”和“P”作为例子。
This idea was very successful, and I showed a demonstration on the PDP-6’s vector display system. The display system could be changed to look like a TV screen.
The characters could be made bigger or smaller, and could be slanted to look like they are written in italics. The characters could also be shown with a border around them or filled in completely.
这个想法非常成功，我展示了PDP-6的矢量显示系统的演示。显示系统可以改变为看起来像电视屏幕。
字符可以变大或变小，并且可以倾斜，看起来像用斜体写的。字符也可以显示为带有边框或完全填充。
(I also played a fun video game on the screen, “Germs” was the game I chose)
（我还在屏幕上玩了一个有趣的视频游戏，“细菌”是我选择的游戏）
I then went to the Massachusetts Institute of Technology (MIT) for 10 years.
Let’s go back to 1989, when I was working at a technology company in Silicon Valley. They made products for Mac computers. I got an invitation to have breakfast with a man named John Warnock.
让我们回到1989年，当时我在硅谷的一家科技公司工作。他们为 Mac 电脑生产产品。我收到一个邀请，要和一个名叫约翰·沃诺克的人共进早餐。
During breakfast, I told him that I created the font system using curves. He looked surprised and worried. It seemed like he and Bob Sproull were friends, and he thought I was going to complain about something.
早餐时，我告诉他我使用曲线创建了字体系统。他看起来既惊讶又担心。看起来他和鲍勃·斯普劳尔是朋友，他以为我会抱怨什么。
I laughed and said to John, “Don’t worry, John. I had an idea a long time ago, but it was really Adobe and you who made it happen.” He laughed a little and seemed to calm down. But I still remember how worried he looked!
我笑着对约翰说：“别担心，约翰。我很久以前就有了一个想法，但真正实现它的是 Adobe 和你。”他笑了几声，似乎平静下来了。但我仍然记得他看起来多么担心！
