Introduction

Model Number: M0420 and M1240

——————————— HISTORY ————————-

The Macintosh Classic was the first Macintosh computer to be sold for less than $1,000. “Classic Mac” is also the name of a series of operating systems developed for the Macintosh family of personal computers from 1984 to 2001 by Apple.

The Macintosh Classic was produced thanks to the success of the Original Macintosh, the Macintosh Plus and the Macintosh SE. The system specifications of the Classic are similar to the original Macintosh computers and include the same 9-inch monochrome CRT display, 512 x 342 pixel resolution and 4 megabytes memory as the old Macintosh personal computers. By not updating the Classic with the latest technology, Apple has guaranteed compatibility with the Mac software and allowed for a lower price. The Classic was 25 percent faster than the Macintosh Plus computer and featured a standard 3-inch Apple SuperDrive floppy drive.

The relatively low price of the Classic and the availability of software for education have led to the popularity of the Classic in education. The Classic was sold alongside the Macintosh Classic II, which was more powerful, in 1991.

Macintosh Classic personal computers include the name ‘Macintosh Classic’ in the lower left corner of the device display. They also generally include the Apple logo from the 90s, which depicted an apple with colored stripes and a bite.
