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. -het Group 0 Commands for Direct-Access Devices ============================================================================== Operation Code Type Command Name ------------------------------------------------------------------------------ 04H M FORMAT UNIT ============================================================================== Bit| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | Byte | | | | | | | | | ============================================================================== 0 | Operation Code | -----|-----------------------------------------------------------------------| 1 | Logical Unit Number | FmtData| CmpLst | Defect List Format | -----|-----------------------------------------------------------------------| 2 | Vendor Unique | -----|-----------------------------------------------------------------------| 3 | Interleave (MSB) | -----|-----------------------------------------------------------------------| 4 | Interleave (LSB) | -----|-----------------------------------------------------------------------| 5 | Vendor Unique | Reserved | Flag | Link | ============================================================================== "With the first link, a chain is forged.
