DS3800HMPF1F is a Microprocessor Controller Board (8086 Micro Computer) manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Control Systems. A microprocessor board, often referred to as a development board or single-board computer (SBC), is a hardware platform that integrates a microprocessor or microcontroller along with supporting components such as memory, input/output interfaces, and power management circuitry. These boards are designed to facilitate the development and testing of electronic systems and applications. A microprocessor controller board is a central component in many electronic systems, serving as the brain that manages and coordinates various tasks and functions. Here's a breakdown of what typically goes into designing one:


  • Microprocessor: Select a microprocessor suitable for real-time control tasks, such as ARM Cortex-M series or FPGA-based solutions.
  • Analog Input/Output Modules: For interfacing with sensors and actuators, including pressure transducers, temperature sensors, and servo valves.
  • Digital Input/Output Modules: For handling digital signals and communicating with external devices.
  • Communication Interfaces: Ethernet, CAN bus, or serial interfaces for communication with external systems or human-machine interfaces (HMIs).
  • Power Supply: Stable power sources with overvoltage and overcurrent protection to ensure uninterrupted operation.
  • Safety Features: Redundancy, fault detection, and fail-safe mechanisms to ensure safe operation under all conditions.
  • Signal Conditioning Circuits: Amplifiers, filters, and signal conditioning circuits to process sensor signals accurately.
  • Watchdog Timer: To monitor the system's operation and reset it in case of failures or malfunctions.


  • Sensor Interface: Use analog input modules to interface with sensors, ensuring accurate and reliable measurement of parameters like temperature, pressure, and flow rate. Implement signal conditioning circuits to filter and amplify sensor signals for precise measurement.
  • Actuator Interface: Utilize analog or digital output modules to control actuators such as servo valves and motor drives. Implement closed-loop control algorithms to regulate turbine speed, fuel flow, and other critical parameters.
  • Communication Interfaces: Integrate communication interfaces like Ethernet or CAN bus for data exchange with external systems, enabling remote monitoring and control. Implement communication protocols suitable for industrial applications, ensuring compatibility and reliability.
  • Power Supply and Safety Features: Design robust power supply circuits with backup systems and protection mechanisms to ensure continuous operation and prevent damage to the controller board. Incorporate safety features such as redundancy, fault detection, and emergency shutdown circuits to safeguard against potential hazards.
  • Microprocessor and Control Algorithms: Select a microprocessor with sufficient processing power and memory resources to execute control algorithms in real-time. Develop control algorithms for turbine speed regulation, load balancing, and fault detection, incorporating feedback loops for closed-loop control.


  • Component Placement: Arrange components strategically to minimize signal interference and optimize thermal management. Group related components together to simplify routing and ensure efficient operation.
  • Signal Routing: Route sensitive analog signals away from noisy digital circuits to minimize interference and maintain signal integrity. Use proper grounding techniques, including star grounding and ground planes, to reduce noise and improve system performance.
  • EMI/RFI Protection: Implement shielding and filtering techniques to mitigate electromagnetic interference (EMI) and radiofrequency interference (RFI), ensuring reliable operation in harsh industrial environments.

What is the difference between a microprocessor and a microcontroller?

A microprocessor is a general-purpose processing unit that requires external components (such as memory and peripherals) to function as a complete system. In contrast, a microcontroller integrates the CPU, memory, and I/O peripherals on a single chip, making it a self-contained computing device suitable for embedded applications.

What are the common applications of microprocessor controller boards?

Microprocessor controller boards find applications in a wide range of industries and systems, including industrial automation, robotics, automotive electronics, consumer electronics, IoT devices, medical devices, and more.

How do you program a microprocessor controller board?

Programming a microprocessor controller board involves writing software (often referred to as firmware) in a programming language such as C, C++, or assembly language. The firmware is then compiled and loaded onto the microprocessor controller board using a development environment and programming tools specific to the microprocessor architecture.
