1987 also marked the introduction of the AppleShare product, a dedicated file server that ran on any Mac with 512 kB of RAM or more. A common AppleShare machine was the Mac Plus with an external SCSI hard drive. AppleShare was the #3 network operating system in the late 1980s, behind Novell NetWare and Microsoft's MS-Net. AppleShare was effectively the replacement for the failed Macintosh Office efforts, which had been based on a dedicated file server device.
