TheMacintosh SEis apersonal computermanufactured byApplebetween March 1987and October 1990. This computer marked a significant improvement on theMacintosh Plusdesign and was introduced by Apple at the same time as theMacintosh II. It had a similar case to theoriginal Macintoshcomputer, but with slight differences in color and styling.

Features

The SE\'s notable new features, compared to its similar predecessor theMacintosh Plus, were:

    Firstcompact Macintoshwith an internaldrive bayfor a hard disk (originally 20MB or 40MB) or a second floppy drive.
  • First compact Macintosh that featured an expansion slot (SE stood for \"System Expansion\").
  • Used theApple Desktop Bus(ADB), introduced with theApple IIGS, for keyboard and mouse interface.
  • ImprovedSCSIsupport with faster data throughput.
  • Better reliability and longer life expectancy due to the addition of a cooling fan.

The SE was designed to accommodate either one or two floppy drives, or a floppy drive and a hard drive. After-market brackets were designed to allow the SE to accommodate two floppy drives as well as a hard drive, however it was not a configuration supported by Apple. In addition anexternal floppy disk drivecould also be connected, making the SE the only other Macintosh besides theMacintosh PortableandMacintosh IIwhich could support three floppy drives, though its increased storage, RAM capacity and optional internal hard drive rendered the external drives less of a necessity than for its predecessors. After Apple introduced theMacintosh SE/30in January 1989, a logic board upgrade was sold by Apple dealers as a high-cost upgrade for the SE, consisting of a new SE/30 motherboard, case front and internal chassis to accommodate the upgrade components.

Single-floppy SE models also featured a drive access light in the spot where the second floppy drive would be.

Additionally the SE had a special PDS slot that allowed for expansion cards, such as accelerators, to be installed. The SE can be upgraded to 50MHz and more than 5MB with theMicroMacaccelerators. In the past other accelerators were also available such as the Sonnet Allegro. Since installing a card required opening the computer\'s case and exposing the user to high voltages from the internalCRT, Apple recommended only authorized Apple dealers to install cards and sealed the case with then-uncommonTorxscrews.

AnEaster Egghidden in the ROMs had four images of the development team.

The Macintosh SE ROM size increased from 64 KB in the original Mac to 256 KB, which allowed the development team to include anEaster Egghidden in the ROMs. By jumping to address 0x41D89A or reading from the ROM chips it is possible to display the four images of the engineering team.

The SE andMacintosh IIwere the first Apple computers since theApple Ito be sold without a keyboard. Instead the customer was offered the choice of the new ADBApple Keyboardor theApple Extended Keyboard.

Apple produced ten SEs with transparent cases asprototypesfor promotional shots and employees. They are extremely rare and command a premium price for collectors.

Macintosh SE FDHD

Originally the SE could use only Single Sided Double Density (SSDD) (400KB) and Double Sided Double Density (DSDD) (800KB) formatted floppy disks. In August 1989, Apple introduced theMacintosh SE FDHDwith the newSuperDrive, a floppy disk drive that could handle 1.4 MB High Density (HD) floppy disks.Originally marketed asFDHD(FloppyDiskHighDensity\"), later some Macintosh SE FDHDs were labeledMacintosh SE Superdrive, to conform to Apple\'s marketing change with respect to their new drive. HD floppies would become the de facto standard on both the Macintosh and PC computers from then on. An upgrade kit was sold for the original Macintosh SE which included newROMchips and a newdisk controllerchip, to replace the originals.

The SE FDHD was discontinued in October 1990, with the introduction of theMacintosh Classicto succeed it.
