The 8MHz Motorola processor may have remained the same but the Macintosh Plus brought much-needed expandability to the Macintosh line. It was the first to support 800k double-sided floppy disk drives, standard 30-pin SIMM RAM modules and SCSI devices such as hard disk drives, CD-ROM drives and printers. Macintosh Plus shipped with 1MB RAM in standard configurations but was upgradable to 4 MB. The Plus was the first Mac to make a real footprint on public education and they stayed inside of schools well into the 1990s.

This machine features 1 MB RAM and an extended keyboard.
