In this case, the DEC-machine-facing side is the MMJ. (at least that is my understanding) Mine too. But he was asking for a MMJ to DE9 adapter as well. And I was pointing out that the (most) common adapter is not IBM PC compatible. I don't believe that the most common MMJ adapters are NOT PeeCee compatible. I have and I have come across manymnay more that are PeeCee compatible that those that are not. The original 9-pin pinout was abandoned pretty early on in the MMJ adapter history. See the OpenVMS FAQ for actual part number for these adapters. http://www.hoffmanlabs.org/vmsfaq/ Maybe I'm wrong. But I have a number of MMJ-DE9 adapters, received from multiple sources, but I do not have a single one which is PC compatible. Johnny
