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 tired hooking up my multisync monitor I have hooked up to my DEC 3000, but I don't think the graphic card is set to a setting within the monitor's range, as nothing shows up. Do the DEC 3000 have a VGA port? It does not. In that case, I would probably suspect the cable just as much as any possible frequency issues... Johnny
