ZuluSCSI Compact RP2040
ZuluSCSI Compact RP2040
A compact, high-performance SCSI storage emulator.
This is a compact model in the ZuluSCSI series, featuring a dual-core RP2040 microcontroller. It can be used with a wide range of retro computers with SCSI interfaces, including Classic Macintosh, Amiga, X68000, and PC-98.
Simply place a disk image (or CD-ROM ISO) with the correct filename on an SD card, and it will be recognized by the SCSI host. It can emulate up to 7 SCSI devices (HDD, CD-ROM, Zip, tape, etc.) simultaneously. It supports FAT32 and exFAT.
