[comp.periphs.scsi] Teac FD235JS Info needed

Harvey_Taylor@mindlink.bc.ca (Harvey Taylor) (05/14/91)

        I am trying to get a TEAC Scsi Floppy (FD-235JS [4/2/1Mb])
    to work on my Amiga.

        At present I have two problems. The FC-1-01 Software Spec. is out
    of print & TEAC says they won't have copies until the end of the month.
    The drive seems to be different from the Hardware Specification which
    I received with the drive. Specifically, at the back of the drive there
    is now a row of shorting blocks labelled from front to back:

            AC AE IR RY D2 D1 D0

        The factory config was AE & D0 shorted. I would like to know how to
    configure these jumpers for auto density sense. Can anybody help?
        Incidentally, most of the other jumpers (on the FC-1) are not
    documented. I mean the User settable blocks:

        EJC J H G F LEV HDS STL PAR MON

        PAR, MON are the only two documented in the hardware specification
    I have. Does anybody have more complete docs?

        Regarding the lack of the FC-1-01 Software Spec., I need to know
    the SCSI CDB for the format command. The generic form is below. Can
    anybody fill in what the Vendor Specific fields require? ie byte 2 and
    byte 5, bits 7&6.
        Any help you could offer in this matter would be most appreciated.
