Can anyone advise me if an ST506 is SCSI compatible? I have one from my old CPM system that I'm thinking of including in my AT setup. Thanks in advance. Bob

The ST506, however, set the standard which most AT machines use. Western Digital, etc., controllers all use the ST506 standard. SCSI and ESDI are different standards. Art Boyne, boyne@hplvla.HP.COM

There are 3 "common" interfaces on PC's today: ST506/412 SCSI ESDI Each is unique and cannot be mixed normally. There are available scsi to 506 adaptor boards (about $100 - $150) but that is sort of defeating the purpose. Are you sure that your AT has an SCSI interface? If has one of the standard controllers (ie WD1002 - WD1003 , OMTI 510(?) etc.) then it is already a 506 type interface and all you would have to do is connect up the drive and power. On the other hand .. why would you want to do this? The 506 is a 5Mb (formatted) 80ms drive. It hardly seems worth it. Unfortunately much of the technology that we would have happily given up parts of our bodies for a few years ago is now more approiate for a museum. Does anybody remember a Base 2 printer or a Morrow 27meg 14inch! winchester system? Unfortunately the basements of hackers nationwide (mine too) are littered with such equipment.
