Anyone know if there is a way to read the data files from the DU 640 without an external floppy drive? If an external computer link is required through the DB25 connector, are there some simple windows10 compatible programs that can interface directly with the DU 640? Can the DB25 be converted to USB with one of the special serial-floppy-to-USB interfaces available for the old Funuc NC machines for example? Does anyone know if the serial floppy drives for the DU 640 are still available anywhere?

To say that the DU600 series specs use old technology is being kind.  The floppy disk drive that was used on them required an internal interface and to the best of my knowledge, no one ever used a converter to make one work outside of the internal spec connection.  The connection to the floppy disk drive was also NOT a serial connection.  There was an internal circuit board that converted a SCSI connection to the IDE connection found inside of the floppy drive case.  To update the spec to use the external floppy disk drive you would need the specific internal interfact and rear panel connector assembly as well as the drive itself.  I seriously doubt that Beckman would still have any of them as the obsoleted the DU600 series almost 10 years ago and I have no idea about any other availability after I retired in 2012.  There was a program called WinConnect that was put out by Beckman to interface a DU600 series to a PC but again, I really don't know if it is still commercially available from Beckman.  I have been helping another researcher with the same issue but as of this point in time I have not been able to come up with a copy of the program myself.
