Whether it was plug board switches or punched paper Programming these early computers was the realm of experts.

无论是插板开关还是穿孔纸，为这些早期的计算机编程都是专家的领域。

There was also a plug board at the front of the machine that allowed pairs of letters to be swapped.

机器前面还有一个插板，可以交换成对的字母。

Finally, in addition to plug boards and punch paper, there was another common way to program and control computers pre-1980: panel programming.

最后，除了插板和穿孔纸，还有另一种 1980 年代以前的计算机编程和控制的常用方法：面板编程。

Instead of storing a program as a physical plug board of wires, it became possible to store a program entirely in a computer's memory.

不再将程序存储为物理接线板，而是将程序完全存储在计算机内存中。

Finally, there was a plug board at the front of the machine that allowed letters coming from the keyboard to be optionally swapped, adding another level of complexity.

最后，机器前方有一个插板，可以把输入键盘的字母预先进行替换，又加了一层复杂度。

If you had your own enigma machine and you knew the correct rotor and plug board settings, you could type in XWDBJ and hello would come out.

如果你有自己的谜机，并且知道正确的转子和插板设置，你可以输入 XWDBJ，你好就会出来。
