AppleCD 150

Background

AppleCD is a range of SCSI-based CD-ROM drives manufactured and sold from the late 1980s to late 1990s. Earlier AppleCD drives required a CD caddy in order to be used, while later models used a tray-loading mechanism. The original model introduced in 1988 was simply called the AppleCD SC. Several other models were made, including the AppleCD SC Plus, 150, 300, 300 Plus, 300e Plus, 300i Plus, 600e, 600i, and 1200i ('e' representing an external drive, and 'i' representing internal; model number also represents data reading speed in KB/s)
