The Apple Macintosh Plus features an 8 MHz 68000 processor, 1 MB of RAM, and an 800k disk drive in a beige or platinum all-in-one case with a 9" monochrome display.



The Macintosh Plus was the first Macintosh to have a double-density 800k disk drive, a SCSI port to allow external expansion, and RAM slots to allow the RAM to be expanded beyond the pre-installed limit.



A model for the education-only market was branded "Macintosh Plus ED."
