Rephlux Roland S550 SCSI Interface

Finally - a 3rd-party SCSI Interface for your Roland S550. It is fully compatible with the S550, plus has one special feature: it supplies termination power to the SCSI bus, thus enabling external units (such as ZuluSCSI) to not require external power. This is an HD5-IF SCSI hard drive interface board clone, exactly duplicating the original's features.  Additionally, it includes an internal 50-pin SCSI jack in case you want to put your SCSI drive inside your S550 or if you want to replace your floppy drive's physical location with a SCSI HDD (again, such as a Internal ZuluSCSI). Comes with all hardware, installation, and all usage instructions. No soldering or drilling necessary.
