Sony CDU561-10 2x SCSI Internal CD-ROM Drive Half-Height 5.25in 1993

The Sony CDU561-10 is a half-height 5.25-inch internal CD-ROM drive with a SCSI interface, manufactured in July 1993 at Sony's ASCO Togane facility in Japan. It runs at 2x speed and connects via a 50-pin SCSI ribbon cable, making it compatible with SCSI host adapters common in workstations and servers of the early-to-mid 1990s. The drive carries TUV, UL, FCC, and CSA certifications and requires 5V and 12V DC power.

Applications

The CDU561-10 dates from the early SCSI CD-ROM era of the late 1980s through mid-1990s, when SCSI was the dominant interface for high-performance optical storage in workstations and desktop PCs. Drives like this were commonly paired with SCSI host adapters such as the Adaptec AHA-1542 or similar cards in platforms including Apple Macintosh, Silicon Graphics workstations, Sun Microsystems SPARCstations, and high-end IBM-compatible PCs running DOS, early Windows, and Unix variants. Today the CDU561-10 is sought by vintage computing enthusiasts restoring period-correct systems, as well as collectors maintaining early CD-ROM-era hardware in working order. It is compatible with any system equipped with a 50-pin narrow SCSI host adapter and a standard 5.25-inch half-height drive bay.
