booting rt11 v5.1 on an 11/45

Tony wrote... I will get that information the next time I go down and work on that machine. Possible, but... xxdp (both v1 and v2.5) works, and vtserver (which is of course highly dependant on the serial port) works. I've tried a few different DL11-W's, all the same. I have this funny feeling it doesn't have a good line clock. I *DID* run a diagnostic that is supposed to be fairly thorough... Below is the output. Of course, the docs don't tell me what this output means, nor do I have source to dig in to (not that I am good with macro11 yet). But here's the diag output: @DL CHMDLE0 XXDP+ DL MONITOR BOOTED VIA UNIT 0 28K UNIBUS SYSTEM ENTER DATE (DD-MMM-YY): RESTART ADDR: 152010 THIS IS XXDP+. TYPE "H" OR "H/L" FOR HELP. .R CQKCG1 CQKCG1.BIC DCQKC-G 11/40 & 11/45 INST EXER OPT.CP=145406 OPT.DEV.=000001 PASS #0000 VPC=152114 PSW=000344 PASS #0000 VPC=152114 PSW=030344 PASS #0000 VPC=152114 PSW=030344 PASS #0000 VPC=152114 PSW=030344 PASS #0000 VPC= and the cursor just sits to the right of that last VPC= So can anyone who may have source for that diag and familiarity with macro 11 tell me what this might be pointing to? Other oddities - the DL11-W diagnostic locks up right after it says something like "01 devices under test" on two different DL11-W cards. On the third card, it continues but then says something about LTC bit 7 isn't setting. I find it hard to believe all three cards are bad... especially when they work fine transmitting and receiving 10mb without error under vtserver. But then, perhaps vtserver isn't doing interrupt mode. Thanks for any thoughts! Jay West
