Anyway, here's the entire Wikipedia article for the Macintosh SE:
The Macintosh SE is a personal computer designed, manufactured, and sold by Apple Computer, from March 1987[1] to October 1990. It marked a significant improvement on the Macintosh Plus design, notably due to its modular and expandable functionality, and was introduced by Apple at the same time as the Macintosh II.

The SE retained the same Compact Macintosh form factor as the original Macintosh computer introduced three years earlier, but used the Snow White design language of the Macintosh II. An enhanced model, the SE/30, was introduced in January 1989, although sales of the original SE continued. The Macintosh SE was updated in August 1989 to include a SuperDrive, with this updated version being called the Macintosh SE FDHD and later the Macintosh SE SuperDrive. The Macintosh SE was replaced by the Macintosh Classic, a very similar model that retained the same central processing unit but at a lower price point.
Overview
edit
The Macintosh SE was introduced at the AppleWorld conference in Los Angeles on March 2, 1987. The "SE" is an initialism for "System Expansion".[2] Its notable new features, compared to its similar predecessor, the Macintosh Plus, were:
First compact Macintosh with an internal drive bay for a hard disk (originally 20 MB or 40 MB) or a second floppy disk drive.
First compact Macintosh to feature an expansion slot.
First Macintosh to support the Apple Desktop Bus (ADB), previously only available on the Apple IIGS, for keyboard and mouse connections.
Improved SCSI support, providing faster data throughput (double that of the Macintosh Plus) and a standard 50-pin intern
