Macintosh Performa 520

The Macintosh Performa 520 is a version of the LC 520 that was rebranded by Apple Computer for the consumer market in Japan. It was sold as part of Apple's Performa line from June 28, 1993 until February 2, 1994.

Features
The Performa 520 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 768 KB would allow it to support up to 16-bit color. The logic board was comparable to (though not interchangable with) a Macintosh LC III with a 25 MHz 68030 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 520 came with KanjiTalk 7.1 pre-installed along with System Enabler 403. The last operating system that it supported was Mac OS 7.6.1.
