ZuluSCSI RP2040 is designed as a modern replacement for your old, failing mechanical SCSI hard drives.

The ZuluSCSI RP2040 is a new member of the ZuluSCSI product family, and is powered by the Raspberry Pi Foundation’s RP2040 microcontroller, a dual-core 133MHz ARM Cortex-M0+ processor. Supports synchronous and asynchronous transfers, with read speeds up to eight megabytes/second. A SCSI controller with FAST SCSI and synchronous mode is required to achieve maximum speeds.

ZuluSCSI is a new generation of file-based SCSI HDD & CD-ROM emulators, and represents a fusion of SCSI2SD V5, V6, and concepts from other open source emulation firmware. 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. Features include a full-size SD card slot, can emulate up to 7 separate drives on different SCSI IDs and DIP switch configurable termination.
