Hello CCTech people, I've recently gotten my hands on a nice little PDP-11/23 system. The main console interface is a DLVJ1-M, that I think may not be in the correct configuration (as I think one of the wire-wrap jumpers may have come off). I can't find any manuals for a DLV11 or DLVJ1, so I'll try to explain the problem. Comparing the DLVJ1 to the DLV11-E maintenance print set on BitSavers (not the same device, but mine appears to be identical to the one in the print set), I've noticed all the jumpers are the same between both except for one block. There's a block of jumpers that looks like: Z? ?Y 0? ?W 1? ?K 2? ?V 3? ?N Which in the maintenance print set has jumpers 0, 1, 2, 3, and N connected to one another. Whereas on my DLVJ1 only 0, 2, 3, and N are connected. Having no manual that explains anything, I have no idea what the current configuration of mine is. So, my question to all of you here on CCTech is: What is the current configuration of my DLVJ1? And more pressing as a question: Does any one have a manual that explains what all the jumper settings are? I ask all of this because, I believe the jumper that connects to pin one of that block, may have come loose and fallen off, which - I'm thinking - would result in the system reaching an advanced state of non-functionality. (Then again, all it does right now, is console ODT; as I've no mass storage, but I do have an RQDX3 and 9058 distributor.) Thanks in advance for any help. -- C. M. Gauger-Cosgrove
