For sale are new made DLVDB25 cables. The circuit board was designed by D-Bit and released for free. You can read more about the board design here:

http://www.dbit.com/wilson/dlvdb25/

The DLVDB25 is intended to plug into DLV11-J 4-port serial boards, or any board that uses the same pinout, including QBus CPU boards with on-board console/SLUs and some third-party disk controllers with serial consoles, like CMD SCSI controllers.

These cables are assembled from boards ran by The Glitch Works, and use high-quality components throughout. The ribbon cable is approximately one foot (0.3 meter) of Belden 10-conductor rainbow ribbon. The DB25M is a NOS Amphenol part with gold plated pins. The boards have been run on thinner-than-standard FR4 material to allow them to be inserted between the solder buckets on these particular connectors.
