| The Macintosh Performa 400 was introduced in September 1992 as one of the first models in Apple’s Performa line, aimed at the consumer and education markets. Internally, it was nearly identical to the Macintosh LC II, using a 16 MHz Motorola 68030 CPU but retaining the LC II’s 16-bit data bus, which limited its performance compared to full 32-bit systems. It came in Apple’s compact low-profile desktop case and included 4 MB of RAM on the motherboard, expandable to 10 MB via a single 30-pin SIMM slot. It typically shipped with a 40 or 80 MB SCSI hard drive and a 1.44 MB SuperDrive. The Performa 400 had a single LC Processor Direct Slot (PDS) for expansion cards, and video output was handled by built-in graphics hardware with support for resolutions up to 640×480 depending on VRAM configuration. It featured mono audio output and a basic speaker system, consistent with other LC-series machines. This model was sold in various bundle configurations and often included educational or productivity software. Like other Performas, it was marketed through consumer retail outlets rather than traditional computer dealers. It was discontinued in mid-1993 as more powerful 68030-based systems replaced it. |
