Microtutor MTP8080

The Limrose Electronics MTP8080 Microtutor was a sophisticated teaching and development system based on Intel's 8080 processor, released in 1976. This device was designed to help users understand and work with the then-new microprocessors, offering a hands-on approach to learning assembly language programming and microprocessor operations.

Technical Specifications

• Processor: Intel 8080A
• Memory: 1 kilobyte (Two 2114 static 1K × 4-bit RAM chips)
• Input/Output:
  • 8-bit Input Port
  • 8-bit Output Port
  • 8-bit Status Port

Key Features

1. Program Entry: Users could enter assembly language programs using either binary switches (in the initial version) or a 16-key hexadecimal keypad (in the second version, MPT8080 K-1).
2. Observation Capabilities: The system allowed users to observe the address, data, and control signals of the microprocessor during code execution.
3. Execution Modes:
   • Single instruction stepping
   • Single cycle stepping
   • Continuous execution
4. Input/Output: Eight LEDs and eight switches for simple I/O operations. The input and output ports also had connectors for external signals.
5. Expandability: The system was expandable with plug-in cards.
6. Monitor: Featured an advanced "Real-time" monitor.
7. Interrupts: Supported full vectored interrupts.
8. Bus Structure: Buffered data and address buses.
9. Documentation: Came with a comprehensive instruction book.

The MPT8080 Microtutor was widely adopted, including by large organizations like the British Post Office, for training purposes. Its design allowed users to gain practical experience with microprocessors, making it an invaluable tool for education and development in the early days of microcomputing.
