| The Macintosh Performa 475 was introduced in October 1993 as part of Apple’s Performa line, which targeted the home and education markets. Internally identical to the LC 475 and Quadra 605, it used a 25 MHz Motorola 68LC040 processor—essentially a 68040 without the math co-processor—making it one of the most affordable yet capable 68k-based Macs of its time. It featured a compact “pizza box” desktop case and supported up to 36 MB of RAM via a single 72-pin SIMM slot, with 4 MB soldered on the logic board. Storage configurations varied by model, typically including an 80 to 250 MB SCSI hard drive and a built-in 1.44 MB floppy drive. The Performa 475 included a single NuBus-compatible LC Processor Direct Slot (PDS), allowing for expansion options like Ethernet cards or video adapters. Video output was built-in and supported up to 640×480 resolution with 16-bit color, depending on available VRAM. The Performa series often came bundled with software suites, monitors, and even printers, depending on the retail configuration. It was discontinued in April 1996 as Apple transitioned to the PowerPC-based systems. |
