January 16, 1986: Apple introduces the Macintosh Plus, its third Mac model and the first to be released after Steve Jobs was forced out of the company the previous year.
The Mac Plus is also the first Macintosh to include a SCSI port, the main way of attaching a Mac to other devices until Apple abandoned the tech on the iMac G3 upon Jobs’ return. The Mac Plus also boasted an expandable 1MB of RAM and a double-sided 800KB floppy drive.
