Can anyone point me to some detailed doumentation on a MicroVAX 3100?  I'm
not sure what model, but the machine is at least 12 years old.  I got the
machine at an auction.  It won't boot, but all I need is to understand
what the LEDs are telling me.  Any help would be great.

Currently in hangs in the boot with these LEDs displayed.
