The ZuluSCSI Mini RP2040 is an external SCSI emulator that fits in your pocket, and is designed for direct-attach use with any device that has a DB25 SCSI ports, such as most legacy Macintosh computers, and is physically the same form factor as SCSI2SD V5.5. It is equipped with a push-pull style microSD card slot, a USB port, which can be used to provide power, as well as used for firmware recovery.

Hard drive and CD-ROM drive images are stored on a standard FAT32 or exFAT-formatted SD card. The ZuluSCSI firmware looks for file names which adhere to a simple but powerful naming convention, and presents them as the drives to the SCSI host. Each image file represents a SCSI drive.
