Re: DL11 M7800

. A year or two ago I made a cable back before I found this nice DEC branded version so I went through the pin assignment fun then. Update: I now have both a working DL11-W (M7856) and an DL11 (M7800) who connect to my terminal through the DEC cable with part number BC03L-10. I have loaded PD

OK. > For 777560/60 (standard for the console), you want A7/A3 and V4/V5 'in'. I intend to use a serial terminal to access the console via M912 CONSOLE ROM. I believe you're saying to connect A7/A3 and V4/V5, but I still don't understand the pattern. What would A4, A5, A6 and V7, V6, V3

OK. I must be missing something here Does anyone have a M7800 (DL11) set for 9600 b N71 or N81 jumper'd with the default address for use as a serial terminal interface? I understand the other jumpers on the card, but the address and vector jumpers confuse me. I can't seem to find a table or a
