Tecmar Mac Drive

The Mac Drive from Tecmar is the first hard drive to be made available for early Macintosh computers. The Mac Drive was released in 1984, before the Davong MacDisk and Apple Computer's own Macintosh Hard Disk 20.

Features
The Mac Drive contained two half-height 5.25" drive bays, which could contain a 10 MB Tandon TM252 hard disk, a 5 MB removable SyQuest SQ100/SQ306R/Q-PAK drive, or both. It connected to the DB-9 serial port of early compact Macs.

Version 2.0 included a pass-through printer port and allowed the drive to be split into up to 20 partitions to circumvent the limitations of the Macintosh File System.
