The PDP-15 was implemented with TTL-integrated circuits, unlike earlier PDPs, which were built from discrete transistors.

不同于早期的 PDP（其从分散的晶体管构建），PDP-15 通过 TTL 集成的电路实现。

They work both with discrete components such as resistors, capacitors, diodes, and transistors as well as with integrated components such as operational amplifiers.

学生既操作离散元件，例如有电阻、电容、二极体和电晶体，又操作积体元件，例如有运算放大器。
