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.
