系统模块是一个DEC模块化数字逻辑系列，在后来的FLIPCHIP之前。它们通过沿一个边缘的一组22个镀金离散引脚连接到它们插入的单元。

他们使用晶体管逆变器电路，使晶体管饱和运行，以避免依赖严格的公差；他们使用-3V和0V作为逻辑电平。它们旨在用于原型制作和生产，包括旨在避免损坏的设计特征。他们提供设计建议，包括装载规则和接线说明。

此外，特殊模块可用于I/O转换器（至标准内部电压）、总线驱动器、灯和螺线管驱动器、A/D转换、继电器、核心内存驱动器等。

属于同一系列的较大组件提供核心内存测试设备。还有电源、带模块插槽的安装面板、容纳安装面板组的机柜、指示灯面板等。

The system module was a DEC modular digital logic family that preceded the later FLIPCHIP. They are connected to the unit into which they are inserted by a set of 22 gold-plated discrete pins along one edge.

They use transistor inverter circuits that saturate the transistors to avoid relying on tight tolerances; They use -3V and 0V as logic levels. They are intended for prototyping and production and include design features designed to avoid damage. They provide design advice, including loading rules and wiring instructions.

In addition, special modules are available for I/O converters (to standard internal voltage), bus drivers, lamp and solenoid drivers, A /D conversions, relays, core memory drivers, and more.

Larger components that belong to the same family provide the core memory test equipment. There is also a power supply, a mounting panel with module slots, a cabinet housing the mounting panel group, an indicator panel, etc.
