Unlike my DEC 3000, the serial console is an MMJ port and not a DB9 serial port. Does anyone have an excess or spare MMJ to DB9 adaptor, or know where I can purchase an inexpensive one? First of all, you are talking about a DE9, not a DB9 (surprising how many don't know the correct name of that connector). I educate whomever I can, but I have all but given up on the general technical public understanding this. It is rather surprising that this lack of understanding continues... Second, DEC often used a different pinout for a DE9 than IBM did, so you might not be too happy with the adapter, depending on what you want in the end. 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/ -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG Well I speak to machines with the voice of humanity.
