Commodore Amiga 2000 Parallel Port Pinout Configuration

This article provides the complete pinout configuration for the parallel port on the Commodore Amiga 2000. It details the DB25 connector layout, signal definitions, and electrical specifications necessary for connecting printers or developing custom hardware interfaces.

Connector Type and Location

The parallel port on the Commodore Amiga 2000 is located on the rear panel of the computer chassis. It utilizes a standard DB25 female connector, which is compatible with most parallel printers and dongles available during the era of the machine. This interface allows for bidirectional communication, though it is primarily designed for output to printers or input from security dongles.

Pinout Signal Definitions

The following list details the specific function assigned to each pin on the DB25 connector. Users wiring custom cables or interfaces should verify these connections against their peripheral requirements to ensure proper functionality.

• Pin 1: Strobe
• Pin 2: Data 0
• Pin 3: Data 1
• Pin 4: Data 2
• Pin 5: Data 3
• Pin 6: Data 4
• Pin 7: Data 5
• Pin 8: Data 6
• Pin 9: Data 7
• Pin 10: Acknowledge
• Pin 11: Busy
• Pin 12: Paper End
• Pin 13: Select
• Pin 14: Auto Feed
• Pin 15: Error
• Pin 16: Initialize
• Pin 17: Select In
• Pins 18-25: Ground

Electrical Specifications

When interfacing with the Amiga 2000 parallel port, it is critical to adhere to the electrical standards to prevent damage to the motherboard. The port operates at TTL logic levels, typically ranging from 0 to 5 volts. The data lines are capable of sourcing and sinking current sufficient for standard parallel peripherals, but users should avoid connecting high-voltage devices directly to the port. Ground pins are distributed across pins 18 through 25 to ensure a stable return path for signals.
