TheMacintosh LC II is apersonal computer designed, manufactured, and sold byApple Computer from March 1992 to March 1993. The LC II succeeded theLC which would be discontinued, replacing itsMotorola 68020 processor with a68030 and increasing the onboard memory to 4 MB. The LC II was priced at US$1,699, fully $800 less than the original LC when it was introduced.[2]
In September 1992, Apple introduced theMacintosh Performa family of consumer-oriented computers. The LC II was repackaged as the Performa 400. When LC II was succeeded by theMacintosh LC III in early 1993, the LC II continued to be sold in some markets for some time after that. In North America, although the use of the LC II branding ceased, two new Performa models (the 405 and 430) were introduced in its place. In October, the Performa 400, 405 and 430 were all discontinued and a new LC II-based model called the Performa 410 was introduced which became Apple's new entry-level computer.[3]
The LC II was Apple's highest-sellingMacintosh product in 1992.[4]
The LC II retains the original LC's 16-bitsystem bus and 10 MB RAM limit, making its performance roughly the same as the earlier model; speed tests often found that the LC II was often slightly slower. The main benefit of the 68030 processor in the LC II is its onboardpaged memory management unit, whichSystem 7 uses to enable its newvirtual memory feature.[1] Apple had opted to get a quick update to the LC out the door instead of spending the additional time required to do a full architectural update,[5] which would happen the following year with theMacintosh LC III.[6]
The LC II was sold at the same time as theMacintosh IIsi, which was more than $800 more expensive than the LC II, but did not have its 10 MB memory limit, 16-bit data bus, and mono audio output. The IIsi also includes aNuBus expansion slot that the LC II lacks, and can be powered on via a button on the keyboard, unlike the LC range which has a power switch on the back of the unit.[citation needed]

Case: The LC II retains its predecessor'spizza box form factor. The design was updated during the LC II's production run when the auto-inject floppy drive was substituted for a manual-inject unit, while the revised front bezel no longer featured the horizontal indentation aligning with the floppy drive, a defining characteristic of theSnow White design language.
Logic board: The LC II retains much of the original LC's logic board design, including a 16-bit data path and a 10 MB memory limit. These limitations limited the machine's ability to take full advantage of the 68030 CPU.
Storage: The LC II shipped with one floppy drive as standard, with options for 40 or 80 MB hard drives. While the original LC had two internal floppy drive connectors, the LC II has one. About 5% of the LC units sold had two floppy drives, and internal hard disks were becoming common by 1992, so the second connector was removed.[5]
Video: The LC II's logic board has one video RAM slot, which is filled with a 256 KB SIMM as standard; the high-end configuration was shipped with a 512 KB SIMM instead. VRAM SIMMs from the original LC are supported in the LC II.[5]
Upgrades: Apple sold a $599 upgrade kit that replaced the LC II's logic board with that of the LC III.[4][7]
