Apple PowerCD
The Apple PowerCD is a portable CD player that Apple sold from 1993. It plays audio CDs on its own or through a stereo, shows Kodak Photo CDs on a television, and acts as a single-speed SCSI CD-ROM drive for a Macintosh when it sits on its base. It is a re-badged version of the Philips CDF-100.[1][2] Apple's guide notes that the PowerCD name was a trademark of ZCI, Inc. of Dallas.[2]

Controls and connections
[edit | edit source]The top of the player has the message display, the disc compartment lid and the playback buttons. The back carries the Open button, the power switch, the video/audio port for a television, the battery compartment door, the headphone port and its volume control, the sound output port for an amplifier or powered speakers, the power adapter port, the SCSI port, the SCSI ID switch and the base lock/unlock switch. The power adapter plugs into a socket on the side of the base. A remote control, running on two AAA cells, came with the player.[2]
The SCSI ID is preset to 3 and is changed with two small buttons above and below the number; Apple says not to use ID 0 on a Macintosh with a built-in hard disk. The Macintosh needs the PowerCD software and QuickTime, installed from the PowerCD Setup disk with the Installer.[2]
Hardware
[edit | edit source]The player and base are separate units. On 68kMLA, a member who took a base apart warns that the DB-25 connector between player and base is not a SCSI port and the player must never be connected to a Macintosh SCSI port directly; a TinkerDifferent member who opened a base in 2025 found two boards with through-hole electrolytics, and another member identified an NCR SCSI chip on the larger board.[3][4] One TinkerDifferent owner found the PowerCD in two colours, a platinum grey and a bluer grey.[5]
Known faults
[edit | edit source]The fault most often reported is a disc that will not spin, sometimes with "ERR" on the display. Owners on 68kMLA and TinkerDifferent traced it to the grey spindle hub having been pushed down onto the motor, probably by people pressing discs on too hard; lifting the hub slightly with a small screwdriver freed the motor.[6][5] The Apple PowerCD Troubleshooting Guide has the details and Apple's own troubleshooting list; the Apple PowerCD General Maintenance page covers batteries, care and dismantling.
