Workgroup Server 9150

See also: Apple Workgroup Server

The Apple Workgroup Server 9150 is the only Apple Workgroup Server model not based on a desktop Mac. It featured an 80 MHz (speed bumped to 120 MHz in April 1995) PowerPC 601 board in a Quadra 900 style case.^[3] The internal bay of the 950 case was filled with a tape backup drive. Atypically, the floppy drive was moved to the bottom of the case, the only Macintosh that ever used this configuration, and uses a regular Mac DA-15 video connector instead of the unusual internal video connector of the other early Power Macintoshes.^[4]
