Tested 1997 Macintosh AppleCD 12X SCSI internal CD ROM drive Matsushita CR-507-C
Matsushita/Panasonic made this drive in 1997 as their model CR-507-C, Apple resold it as their AppleCD 12X, with their part number 678-0109. Here is a working 12X tray-loading internal SCSI CD ROM I pulled from a Power Macintosh 7300.
