Description
Commodore Amiga 500 Internal Dual Floppy Disk Drive Interface
In essence, this plug-in adapter for the Amiga 500 facilitates the simultaneous use of two types of floppy disk drives: a Gotek drive for quick and easy access to digital images of floppy disks, and a traditional mechanical drive for compatibility with original floppy disks.

- Enhanced silk screen layer for better visibility and clarity.
- Rerouting conducted with minimized traces for improved signal integrity.
- Bill of Materials list updated with the changes.
