IIgs using hard disk 20 - test-drb@ccmp.vtda.org

Doug:
        It was through the floppy port. It used a special boot disk with a
"HD20" init to make it work.
        I haven't opened mine recently, but the drive only had one I/F
connector on it but I can't remember the pin count. I could look tonight.

  BUT... predating that was a "Macintosh Hard Disk
20" that was not scsi.
 Rather is was some drive (don't know what kind, but MFM seems sensible
 enough) that used a special adaptor board that enabled it to plug into
 the disk drive port on a bunch of the older macs. It was all enclosed
 (drive, power supply, adaptor board) in one nice zero footprint beige
 case (back when beige meant brown, and not grey like "beige" computers of
 today). 
In spite of the now long-extant senility, I seem to recall that these
interfaces through the serial port, not the floppy port.
