Original Description:
The Apple Hard Disk 20 (HD20) was an external 20 MB hard drive for the Macintosh, introduced in 1985. This was during the earliest days of the Mac’s history, before the introduction of SCSI support, so the HD20 connected to the Mac’s floppy port. Despite sharing the same DB-19 connector as a floppy drive, the HD20 used an entirely different communication method, making it something of a hardware freak. When SCSI support was introduced in 1986, the HD20 faded into obscurity.Been on ...the self with the floppy drives since the nineties. Powers up and runs quietly
