NeXT Sony 1 X EXTERNAL CD-ROM DRIVE

!

The NeXT External CD-ROM Drive provides immediate access to large stores

of information. With a capacity of up to 680 megabytes of stored data, the NeXT

™  External CD-ROM Drive is ideal for people who desire an efficient means to generate a backup copy of their system software from a CD-ROM disc. CD-ROM discs also provide a convenient way to update or load additional software onto your hard disk drive or network server. You can

copy industry standard files such as TIFF, EPS, RTF, or text, into applications running on

your NeXT computer, or move the data onto your hard disk, to take advantage of all the

editing options available on NeXT systems. The drive also allows you to explore the multitude of CD-ROM discs holding digitally recorded text, graphics, and sound files, as well as listen to your favorite audio CDs by using the drive’s RCA jacks. Switch back and forth, as you desire.

The NeXT External CD-ROM Drive supports the major file formats, High Sierra,

ISO-9660, and Rockridge, making it possible to select from an expansive range of available

CD-ROM titles, as well as high-quality color and PostScript ® image files.

680 MB capacity Large enough for full system software releases. Unlike having a software

release on floppies, the single CD-ROM is convenient for updating your

hard disk. You don’t have to constantly swap floppies.

reading large image or text files.

single drive.

To use the NeXT External CD-ROM Drive, you will need a

NeXT computer, a SCSI-I–to–SCSI-II cable, as well as a SCSI

terminator if the drive is the last external SCSI device connected to

your NeXT computer. You will also need NeXTstep Release 2 or

later. For support of the Rockridge format and for sharing CD-ROMs

across a network, NeXTstep Release 3 is required.
