Macintosh Performa 575

The Macintosh Performa 575 is a version of the LC 575 that was rebranded by Apple Computer for the consumer market in Japan. It was sold as part of Apple's Performa line from February 1, 1994 until April 1, 1996.

Features
The Performa 575 was an all-in-one desktop Macintosh with a built-in 14" display from Sony. It contained 512 KB of VRAM that could support up to 8-bit color at a resolution of 640 x 480 pixels; upgrading the VRAM to 1 MB would allow it to support up to 16-bit color. The logic board was comparable to (though not interchangable with) a Macintosh LC 475 with a 66/33 MHz 68LC040 processor and a 32-bit LC PDS slot. One 72-pin  slot allowed RAM to be upgraded from the base 4 MB soldered onto the motherboard, to a maximum of 36 MB. Hard drives were connected through a SCSI bus. The built-in floppy drive supported 1.44 MB high-density disks.

The Performa 575 came with System 7.1P6 pre-installed along with System Enabler 364 and a home software bundle. The last operating system that it supported was Mac OS 8.1.
