<P> The Macintosh Hard Disk 20 was the first hard drive developed by Apple Computer specifically for use with the Macintosh 512K . Introduced on September 17 , 1985 , it was part of Apple 's long awaited solution toward completing the Macintosh Office ( a suite of integrated business hardware & software ) announced in January 1985 . It would be over a year more before Apple would release the file server software AppleShare that would link all of the hardware together . By that time the SCSI interface introduced on the Macintosh Plus in January 1986 , would accommodate far faster and more efficient hard drives , rendering the Hard Disk 20 virtually obsolete . </P>
