I have a VS3100 m38 also, running NetBSD 1.5 on the built-in mono adaptor. I also have the VR262 19" mono screen to go with it. I can take my cable home tonight, where my multi-meter is. I can double check for you... BTW, are you not going to use color (adaptor) in it? --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818 ! -----Original Message----- !

I have a vaxstation 3100 m38 running NetBSD, and I'd like to be able ! to use the local monochrome display. I've removed the SPX ! color adapter, ! and made up a cable according to the pinouts on Kee's VS3100 page. His ! pinouts are composite on pin 9 and ground on 3 for a BC23K-03 cable. ! However, with the cobbled cable attached, I don't get any output. ! Question 1: Did I miss a jumper on the mainboard? ! Question 2: I assumed that the pins were numbered in the ! same order as ! an AUI ethernet connector. Looking at the female, I have 1-8 ! right-to-left, and 9-15 R-t-L. Is this correct? ! Question 3: I'm using an IBM Power17 display. Multisync, ! separate-sync, ! composite-sync and sync-on-green capable, I would think it would work ! with mono input on the green. It does work fine with the SPX adapter. ! Question 4: I also have a Digital VR160 display, but everything I've ! read implies that it won't do monochrome. Is that true? ! ! Has anybody been successful with a monochrome display on ! this box? Any ! help would be most welcome. ! ! Doc !
