Apple Macintosh Performa 405 Specs

All Macintosh Performa Models | All 1993 Models | Dynamically Compare This Mac to Others


Apple Macintosh Performa 405The Apple Macintosh Performa 405 features a 16 MHz 68030 processor, 4 MB of RAM, 256k of pre-installed VRAM, and an 80 MB hard drive in a compact, easy-to-upgrade "pizza box" case. The Performa 405 is identical to the Performa 400, but the 405 shipped with a 12" Apple color monitor but only 256k of VRAM.

The educational version of the Performa 405 is the LC II.

Please note that the picture is an LC 475/Performa 475 and the Performa 405 design is similar, but has a "flatter" front with a groove rather than a sleek curve. EveryMac.com eventually will swap out this photo with a more precise one.
