Hi. I am preparing my PDP-11/73 for my exhibition at the VCFe. I wane get the DHV11 (M3104) and a four port DLV11J colne to work. At the moment I get upon boot: autoconfig: warning: more than three handlers for device cn on line 38. dhv ? csr 160440 vector 310 didn't interrupt. ra 0 csr 172150 vector 154 vectorset attached ra 1 csr 160334 vector 764 vectorset attached rx ? csr 177170 vector 264 skipped: No CSR. tms 0 csr 174500 vector 260 vectorset attached ts 0 csr 172520 vector 224 attached cn 1 csr 176540 vector 344 no address found for kl/dl-11 Extract from /etc/dtab: # grep '^[a-zA-Z]' /etc/dtab dhv ? 160440 310 5 dhvrint dhvxint # dhv terminal mux ra ? 172150 154 5 raintr # uda50, rqdx1/2/3 ra ? 160334 764 5 raintr # uda50, rqdx1/2/3 rx ? 177170 264 5 rxintr # rx01/02 tms ? 174500 260 5 tmsintr # tmscp driver ts ? 172520 224 5 tsintr # ts11 driver cn 1 176540 344 5 cnrint cnxint cn 2 176550 354 5 cnrint cnxint cn 3 176560 364 5 cnrint cnxint What is wrong with the "cn" devices? I checked the CSRs of the DHV11 and the DLV11J cards with the "show qbus" command on a MicroVAX 4000-200 to be sure that the CSRs are where I am expecting them: Scan of Qbus I/O Space -20000120 (760440) = 009D DHQ11/DHV11/CXA16/CXB16/CXY08 -20000122 (760442) = F081 -20000124 (760444) = 0000 -20000126 (760446) = 0000 -20000128 (760450) = 0000 -2000012A (760452) = 0000 -2000012C (760454) = 0000 -2000012E (760456) = 0000 -20001940 (774500) = 0000 TQK50/TQK70/TU81E/RV20/KFQSA-TAPE -20001942 (774502) = 0BC0 -20001D60 (776540) = 0000 DLV11J -20001D62 (776542) = 0000 -20001D64 (776544) = 0080 -20001D66 (776546) = 0000 -20001D68 (776550) = 0000 DLV11J -20001D6A (776552) = 0000 -20001D6C (776554) = 0080 -20001D6E (776556) = 0000 -20001D70 (776560) = 0000 DLV11J -20001D72 (776562) = 0000 -20001D74 (776564) = 0080 -20001D76 (776566) = 0000 -20001F40 (777500) = 0020 IPCR -20001F70 (777560) = 0000 -20001F72 (777562) = 0000 -20001F74 (777564) = 0080 -20001F76 (777566) = 0000 -- tschüß, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
