There is a way to use ESDI drives with an SCSI interface (such as a PC with an SCSI card or a Sun workstation). It seems that Adaptec makes a translator which allows you to connect ESDI drives to SCSI controllers. ( 2/15/94, Willem Jan Withagen ) I have an Emulex MD-21 which is the device you want. It is an ESDI to SCSI converter. It controls both 10 and 15 mbit/sec drives and provides a SCSI-1 interface on the other side. The interface will handle two ESDI drives as logical units 0 and 1. (Suns and NeXTs recognize the 2nd logical unit – anyone know if apollos do?) I’ve had this board connected a wide range of systems (NeXT, Sun, Mac, Apollo) without any problems. This board is a discontinued item, but you can buy them from Sun resellers since they were commonly used in Sun shoeboxes. I paid $40 for mine from such a vendor.
