The Macintosh SE was a serious workhorse with the capacity for expansion. It is manufactured by Apple between March 1987 and October 1990. It also included the option for having an internal hard drive with a floppy drive, or two floppy drives. (Each could, however, only take a double-density disk -- the FDHD version of the SE came out later.) The Macintosh SE was a very stable Mac to work on. Its design stood out with the vertical grill bars at the bottom of the machine. These would be streamlined and, in fact, be gone with the Macintosh Classic and subsequent all-in-one Macs.
