1. Variable read rate. Actual playback speed will vary and is often less than the maximum possible.
2. Intel Pentium III processor with 133 MHz front-side bus (FSB).
3. Standard Hard Disk Drives (HDD) are Ultra2 7200 RPM. Maximum internal capacities assume replacement of standard hard disk drives with the largest supported IBM hard disk drives.
4. Not available from IBM after this date. Business Partner inventory may be available.
