How to Use a Scroll Wheel Mouse on Amiga 500: TruScroll Adapter Guide

How to Use a Scroll Wheel Mouse on a Commodore Amiga

If you are using a Commodore Amiga 500, 1200, or 600 in the modern era, you’ve likely reached for a scroll wheel that isn’t there. The original Amiga “tank mouse” was a classic, but for modern productivity in Workbench, a scroll wheel is a game-changer.

The good news? You can easily add scroll wheel support to your vintage hardware. This guide covers everything from the TruScroll USB adapter to the software drivers required to get you scrolling.


1. The Hardware: Why You Need a TruScroll Adapter

The Amiga uses a unique 9-pin (DB9) mouse port that is electrically different from modern PC mice. To use a modern optical mouse, you need an intelligent interface.

The TruScroll Amiga Mouse Adapter is the premier choice for enthusiasts because:

  • True USB HID Support: It works with almost any modern wired or wireless USB mouse.

  • Plug-and-Play: No complex hardware modifications required.

  • Low Profile: Fits perfectly in the cramped mouse ports of the Amiga 600 and 1200.

  • Optical Precision: Eliminates the need for cleaning old mouse balls and rollers.


2. Essential Software for Amiga Scroll Support

While the TruScroll adapter handles the hardware connection, AmigaOS (Workbench) needs a driver interpret the scroll wheel signals.

TankMouse Driver

Once you run it you can close the window – the drivers stays in memory and enables the scrollwheel on the TruScroll adapter

The driver also includes a driver installer, once installed it will automatically run at startup if your Amiga boots froom an internal drive

The most widely used software for this is FreeWheel by Alastair M. Robinson, use this down link Freewheel.

  • What it does: It intercepts the wheel data from your TruScroll adapter and tells Workbench windows to scroll up or down.

  • Compatibility: Works on virtually all versions of AmigaOS versions

AmigaOS 3.2+ Users

  1. Safety First: Power off your Amiga before connecting any hardware.

  2. Connect the Adapter: Plug your TruScroll adapter into the amiga Mouse Port.

  3. Plug in Your Mouse: Insert your USB mouse (or wireless dongle) into the TruScroll USB port.

  4. Install the Driver:

    • WithFreewheel running you can scroll the contents of Workbench windows by hovering the mouse over the bottom or side scrollbars and using the mouse scrollwheel
