Description
The Macintosh LC 580 was sold in 1995 and 1996. Like their immediate predecessor, the LC 575, it used the Motorola 68LC040 processor at 33 MHz. However, instead of being based on the LC 475/Quadra 605 like the 575 series was, the 580s are based on the Performa 630 series. This meant a few changes, most of them leading to lower prices, but also lower performance: Most notably, the hard drives of the 580 were IDE drives instead of SCSI drives. Also, the video RAM was no longer mounted on a SIMM, but used 1 MB of the 4 MB of main RAM soldered to the motherboard. Lastly, the Trinitron display of the 575 was replaced with a cheaper shadow mask screen.
