This information is taken from literature provided by Iomega Corporation and applied originally to the 1 GB Jaz. As of March, 1999, the 1 GB is no longer sold and has been replaced by the 2 GB Jaz. The specifications of the 2 GB Jaz should be at least as good as the 1 Gb Jaz. Much of the information below is probably still valid, but should be used with caution.

1. What configurations are available(IDE, SCSI, Internal, External)?

The drive will initially come in two Fast SCSI II versions, an Insider 3 1/2 inch model and a Portable (external) model.

2. What is the suggested retail price for the drive and disks?

Please check our prices at the link given at the bottom of this page.

3. What type of Technology does it use?

4. What are the products features and benefits?

5. What operating systems are supported?

The drive includes software drivers to support either DOS(version 4.x or greater), Windows (3.x), Windows 95 (1.x) or Macintosh OS (7.x). OS/2 drivers are also available from Iomega (OS/2 ver. 2.x or greater). Other operating systems such as Windows NT, Unix and Netware are also compatible, Iomega has technical documents available describing Jaz support for other operating systems.

6. Is a Jaz disk included?

The Jaz drive no longer ships with a Jaz disks. A CD-ROM with the software is included.

7. Which SCSI adaptors can be used?

For best compatibility and performance we suggest using Iomega SCSI adaptors, such as the Jaz Jet PCI SCSI adaptor. In addition, the drive is compatible with most ASPI compatible SCSI adaptors and drivers. We also plan to have an external parallel port SCSI adaptor available for the Jaz drive.

8. Is the Jaz drive bootable?

The Jaz drive can be used as the computers boot disk if configured properly. Normally the drive must be set to SCSI ID 0 and the SCSI adaptor must have a bootable BIOS. For example, the Jaz Jet PCI SCSI adaptor is a bootable adaptor.

9. What computers are supported?

IBM PC and compatibles (386 or greater) and Macintosh (SE or greater). Other computer systems with a SCSI interface may also be compatible. Iomega has technical documents available regarding other systems that are compatible.

10. Can I use a DOS disk in a Macintosh and vice versa?

The Jaz drive, when connected to a Macintosh, can read and write DOS, Windows and Windows 95 formatted disks using Apple's PC Exchange program (2.0 or greater). There are a number of third party vendors that offer software packages that will allow Macintosh Jaz disks to be accessed in DOS and Windows systems.

11. Can the Jaz drive be used as a network shared device?

Yes, if the proper network drivers are used (example: Adaptec SCSI adaptors with Adaptec's Network drivers). The drive can also be used to backup the server when connected to a workstation on the network without any special drivers.

12. General Product description

SCSI ID select switch (0 -7), on/off switch, and an external power supply (brick).
