Macintosh SE/SE FDHD

Introduced: March 1987
Terminated: October 1990


The Macintosh SE was cased in the platinum color that was first seen in later versions of the Macintosh Plus.  Like earlier models, the Macintosh SE was enclosed in a single case.  It was the first Macintosh with an internal hard drive.  Users could choose to have a dual floppy drive as an alternative.  The Macintosh SE was the first Macintosh to contain an expansion slot.  The “SE” in the name stands for “System Expansion.”

The Macintosh SE used the same Apple Desktop Bus that had been used in the Apple IIGS, which allowed for a number of devices to be connected to it. 

The Motorola 68000 processor could run at speeds of up to 8MHz.  The 1MB of RAM was expandable to 4MB.  In 1988, the Macintosh SE was replaced with the Macintosh SE FDHD.  The only difference in the new model was that it contained the new SuperDrive, a floppy disk drive that could handle 3.5” high-density 1.4MB disks.


The Macintosh SE succeeded the Macintosh Plus and offered a number of technical advancements.  The Macintosh SE and the SE FDHD were also noted for improved reliability and a longer life expectancy.

  • The SE was introduced as the low-end cousin of the hot new 16 MHz Mac II. The SE was the first compact Mac with an expansion slot. One of the first add-in cards was an MS-DOS card. Over time, video, ethernet, and accelerator cards became popular accessories. car title loan
