In Figure 1, you can see a Macintosh SE system with a keyboard and a mouse. Previous Apple computers didn’t feature a fan because Steve Jobs thought it was noisy and “inelegant.” The Macintosh II was a full-sized desktop computer, unlike the SE and its predecessors, which were compact computers.Īnother feature that was added with the SE was a cooling fan. In fact, “SE” stands for “System Expansion.” Actually, the Macintosh II, which was released at the same time, also featured expansion slots. The Macintosh SE was also the first Mac to feature an expansion slot, called the PDS (Processor Direct Slot). (The dual drive model didn’t come with an internal hard drive.)Īnother difference between the Macintosh SE and the previous models was the addition of a new bus for connection of peripherals such as keyboard and mouse, called ADB (Apple Desktop Bus). This was the first Macintosh computer to feature an internal hard drive. The most important was the addition of an internal hard disk drive (20 MB or 40 MB) connected to a new internal SCSI port.
This computer, however, came with new features.

It inherited the external SCSI port, the 800 KB floppy disk drive (later upgraded to a 1.44 MB floppy, as we will discuss), and 1 MB of RAM using four SIMM-30 memory modules (allowing you to upgrade the memory to 4 MB) from the Macintosh Plus. The Macintosh SE was based on the same processor (Motorola 68000), had the same size, and used the same screen size and resolution (9-inch black-and-white with 512 x 342 pixels) as the previous Macintosh models (except the Macintosh SE/30, which used a Motorola 68030 processor). Several versions of this computer were released.
