Macintosh SE FDHD

Macintosh SE FDHD

The expandable Classic Mac with high density drives
• Included a 1440K double-sided high-density disk drive - you could have two internal (no internal hard drive) and one external!

If you are interested in upgrading the Mac SE, make sure you see the Premiere Issue of The Mac 512 User Group's Newsletter!

The Mac SE FDHD looked the same as a regular Mac SE.

The only real change from the Mac SE to the Mac SE FDHD was the 1.44MB floppy drives. Otherwise everything else is the same. This provided 4.2MB of floppy-based storage! Plus the drives could read/write MS-DOS (IBM) floppies!

For AppleShare use: System 6.0.x and Finder 6.1 are installed by the AppleShare Client 6.x Installer disk. This machine can be used as an AppleShare file server.

For telecommunications use: Can use 9600 baud modem or lower, anything higher may cause problems. Stock Macintosh SE can be placed on the Internet, with maxed 4MB of RAM memory upgrade.

Hard Drive use: Can use the Apple's HD20 - plugs into the floppy port. Stock Macintosh SE can use any SCSI hard drive (25 pin port on back). SCSI only - Use a 2:1 interleave.

Color use: Aura Systems created an external box which outputted color from a Macintosh SE. I looked into this at one point, very expensive, about $2500.
