[net.micro.apple] Macintosh hard disk question

 Why does Tecmar interface its hard disk for the Mac through the
 RS-422 serial ports?  Why don't they connect it through
 the external disk drive connector?  It seems to me that
 this would be faster than going through the serial ports,
 wouldn't it?
