Either it has detected unix on the internal disk and refused to run it… 😉 or that’s the “Unexpected Interrupt” error.  It means just that, and could be a symptom of more problems than I care to guess at.
Since this is a microvax II, I’d suggest first off that you remove all unnesecarry components, and try booting with only the cpu board. (obviously it won’t boot, but it should get past the self-test)
It the problem is on any other board you’d be able to work it out by process of elemination this way. (remember that qbus is very picky about the order of boards and leaving blank spaces…)

Again, that’s the best way to do it, I’d guess.  Clean all the contacts while you’re at it… never hurts.Regards,  Christopher Smith

Looking for MicroVAX 2 (630QB-A3) Console settings Options

Please take a look at the OpenVMS FAQ — it has a section on the MicroVAX 
console bulkhead and operation, and information on many other topics. 
(This is not the first time this question has been asked, obviously.)

  If you can’t get _any_ output (including simply garbage characters) on
  the console, then you probably have the wrong pinout, or you have a
  hardware or wiring problem.  The OpenVMS FAQ also has the MicroVAX DB9
  pinout — and it’s not the same DB9 pinout that is used on PC systems.
