AppleCD SC Plus

Background

The AppleCD SC Plus was Apple's second CD-ROM drive, a replacement for the AppleCD SC which was introduced in 1991. Identified as model number M3021, just like its predecessor, the AppleCD SC, it used a 1x Read Only Media CD-ROM drive. The Plus could read a CD with up to 750 MB of data over the 650 MB of the AppleCD SC. It had indicator lights, an eject button, mini-phone audio jack, volume knob, and the CD caddy drive on the front of the accessory. On the back there were two 50-pin Centronics SCSI connectors, audio RCA connectors, power input, and a power switch. The AppleCD SC Plus had only minor improvements over the AppleCD SC and it was relatively the same.
