Macintosh LC

The Apple Macintosh LC was introduced in 1990. It ran on the Motorola 68020 clocked at 16MHz. The later LC series would swap this CPU for the Motorola 68030 or higher.

The Macintosh LC was introduced at the same time with the Macintosh Classic which itself was a repackaging of the Macintosh SE. The idea behind the LC line of computers was to introduce a cost-effective computer to be sold to schoolboards. The design was simplified so that assembly of the computer could be robotized, reducing cost.

The LC shipped with 256KByte of Video RAM (VRAM), and could produce an image of 512x384 pixels in 8-bit color. The VRAM was upgradable to 512KByte wich would enable 512x384 in 16-bit color, or 640x480 in 8-bit color.

The LC suffered from a performance problem: The databus was slowing the machine down, and the performance was lower than the 16MHz 68020 based Macintosh II from three years earlier which ran almost twice as fast.

Is it a Quadra? An LC? A Performa?

In 1993 Apple made the decision to rename their Macintosh computers. They introduced three different product names, based on the target audiences. The result of this is that many Macintosh machines are exact duplicates of each other, but just with a different brand name.

  • Quadra line - Business Customers, sold only through Apple resellers.
  • LC line - Education market, sold primarily to schools.
  • Performa - Home consumers, sold in department and electronics stores.

Example: The Macintosh Quadra 605 is the same computer as the Macintosh LC 475 and the Macintosh Performa 475.
