    It makes me wonder if the 8570-x81 and -x61 (similar drives to the 8580-081, -161 and -A16) should be considered to have DBA-SCSI drives, except that the Set Config panel displays would still refer to them like DBA-ESDIs. I guess their onboard

    Thoughts everyone?

    I had not seen this discussion more than three years ago - and don't know what in the link that WBST was referring to, but the "DBA-SCSI" drives he describes are the 40, 80, and 160Mb with the 80C196KB microcontroller (all ESDI and other DBA-ESDI
    controllers use an 80C31): https://ibmmuseum.com/Interrupts/INT13h/INT13h1C0B.htm
