ZuluSCSI Wide SCA is an advanced high performance SCSI storage emulator with support for 16-bit Wide and Ultra Wide SCSI.

Developed by Rabbit Hole Computing, ZuluSCSI Wide is equipped with an 80-pin Single Connector Attachment connector, which carries both power and Wide SCSI signals. ZuluSCSI wide SCA is a single-ended SCSI device, but can be used with nearly all SCSI controllers that support LVD/SE operation, as the SCSI controller itself will fall back to single-ended mode.

ZuluSCSI Wide SCA supports Ultra Wide synchronous and asynchronous SCSI transfers, with read speeds up to 34 megabytes/second.  A SCSI controller with Wide or Ultra Wide SCSI support is required to achieve maximum throughput.

ZuluSCSI is easy to use: Simply place an appropriately named disk image or CD-ROM ISO on your SD card in order to present it for use by your SCSI host system. ZuluSCSI Wide supports both FAT and ExFAT-formatted SD cards of up to 1.5TB in size.
