The LC 580 (a.k.a. Performa 580 and 588) is essentially an LC 575 with a new logic board that supports an IDE hard drive (instead of the more expensive SCSI hard drive used in earlier 500 series Macs) and uses a less expensive monitor.

It also has a video I/O slot that can accept the original TV tuner card Apple created for the Performa series.

Cautions

• Internal HD Format: Cannot See IDE Drives (Apple Knowledge Base 18360) notes that due to changes in the way modern IDE drives are formatted at the factory, early versions of Apple HD SC Setup (ones that come with System 7.5.1 and earlier) will not recognize them. You should boot System 7.5.2 or later and use Drive Setup 1.0.3 or higher with these drives.
• The IDE controller only supports a single device.
• This highest PIO mode this model supports is Mode 3 (11.1 MB/s), Macintosh: Using Third Party IDE Hard Disks
• Serial port normally restricted to 57.6 kbps; throughput with a 56k modem may be limited. See 56k modem page. For more information on Mac serial ports, read Macintosh Serial Throughput.
