Macintosh Classic, Macintosh IIsi and Macintosh LC

The Macintosh Classic is a personal computer designed, manufactured and sold by Apple Computer from October 1990 to September 1992. It was the first Macintosh to sell for less than US$1,000.

Production of the Classic was prompted by the success of the original Macintosh 128K, then the Macintosh Plus, and finally the Macintosh SE. The system specifications of the Classic are very similar to those of its predecessors, with the same 9-inch (23 cm) monochrome CRT display, 512 × 342 pixel resolution, and 4 megabyte (MB) memory limit of the older Macintosh computers. Apple's decision to not update the Classic with newer technology such as a newer CPU, higher RAM capacity or color display resulted in criticism from reviewers, with Macworld describing it as having "nothing to gloat about beyond its low price" and "unexceptional". However, it ensured compatibility with the Mac's by-then healthy software base, as well as enabled it to sell for the lower price, as planned. The Classic also featured several improvements over the aging Macintosh Plus, which it replaced as Apple's low-end Mac computer. It is up to 25 percent faster than the Plus and included an Apple SuperDrive 3.5-inch (9 cm) floppy disk drive as standard. Unlike the Macintosh SE/30 and other compact Macs before it, the Classic did not have an internal Processor Direct Slot, making it the first non-expandable desktop Macintosh since the Macintosh Plus. Instead, it had a memory expansion slot.

The Macintosh IIsi is a personal computer designed, manufactured and sold by Apple Computer, Inc. from October 1990 to March 1993. Introduced as a lower-cost alternative to the other Macintosh II family of desktop models, it was popular for home use, as it offered more expandability and performance than the Macintosh LC, which was introduced at the same time. Like the LC, it has built-in sound support, as well as support for color displays, with a maximum screen resolution of 640 × 480 in 8-bit color.

The IIsi remained on the market for two and a half years and was discontinued shortly after the introduction of its replacement, the Centris 610.

The Macintosh LC is a personal computer designed, manufactured, and sold by Apple Computer, Inc. from October 1990 to March 1992. The "LC" in the name stood for Low Cost—or Low-cost Color, a reference to it being the first affordable color Macintosh computer for the entry level consumer.
