        Hi,

        In case you are interested .....

        The TEAC floppy we are using is the TEAC FD-235HS-300 which includes
        the TEAC FC-1-00 'FDD SCSI Interface Unit', i.e. control board.
        I've had no trouble with this device. By setting hardware straps it
        can be made to automaticaly sense 1M byte and 2Mbyte discs or can be
        hard strapped to one or other.

        I am also using the TEAC FD-235JS-401 which is a 4M byte floppy.
        Again it works fine. We won't be using this in a product however
        since we have to be backwards compatable with existing systems.

        Apollo division (contact Bill Clemmey) are also investigating a
        TEAC SCSI floppy but model FD-235HS-302 which includes the
        FC-1-01 SCSI control board.  This control board does not permit
        the automatic media-sense function we need, it has to be set to
        the media type by a Mode Select command.

        One additional point: TEAC are replacing both versions of the
        FD-235-HS in the new year with drop in replacements.  The new
        spec is better in places (shock is certainly).  We are awaiting
        samples.

        If I can be of assistance please ask.

                Best regards

                        Andy.
