Apple 24X Internal SCSI CD-ROM Drive, 661-1400, 678-0132. Model CR-508C. This drive will work in all Power Macs, or probably any Mac with an internal SCSI bus and an empty drive bay. Of course it can also be put into an external SCSI enclosure.

New in box! There are 3 drives in stock with consecutive serial numbers, AU1875, AU1876, AU1877. I had to open one of the boxes as my search for 661-1400 didn’t produce any results. Contact me for a shipping quote if you would like the CD box to ship inside another box.

Also available is a used Matsushita CR-508. Same drive as above, but without Apple label (no photo).

While it can be used with any Macintosh with internal SCSI and a drive bay, it came as either standard or optional in the Power Mac and Performa 6100 series. Manufactured by Matsushita, CR-503-C.
