DB25 SCSI Micro SD Interface

What is it?

The DB25 SCSI Micro SD Interface is a compact solid-state storage solution for classic Macintosh computers. It connects via the standard DB25 SCSI port found on vintage Macs and emulates a hard drive using a Micro SD card — giving your retro machine fast, silent, and reliable storage without spinning disks.

Compatible with Macintosh Plus, SE, and other early Macintosh computers that use the external DB25 SCSI interface.

Why did you make it?

Finding working SCSI hard drives for vintage Macintosh systems is increasingly difficult and expensive. This interface replaces aging mechanical drives with modern Micro SD storage, making it easier than ever to restore and enjoy classic Macs. No more worrying about head crashes or failed bearings — just plug in an SD card and go.

What makes it special?

• DB25 SCSI connector — plugs directly into the external SCSI port, no internal modifications needed
• Micro SD storage — silent, fast, and far more reliable than original SCSI hard drives
• Broad compatibility — works with Macintosh Plus, SE, and other DB25 SCSI-equipped Macs
• Compact form factor — minimal footprint, easy to store alongside your vintage hardware
• Simple setup — format and use with standard Mac system tools
