DEC H8571-J MMJ adapters?

I've had a hard time finding inexpensive H8571-J equivalent adapters, but I have a huge box of surplus DE9-F to 6-conductor RJ11 adapter kits. I was planning to make up a batch of H8571-J equivalent adapters out of these and some RJ11 to MMJ cords and wondered if anyone else out there could use some? Based on what I've seen on eBay, I suspect I could sell some there, but I wasn't sure if there would be any demand from classiccmp folks as well. I could also wire up some H8571-B equivalent adapters if there is any interest in those as well. Those would actually be simpler to make than the H8571-J. I personally don't need any more H8571-B adapters as I have plenty for the few MicroVAX systems that I have, but they aren't always easy to find. -Toth
