Now that I (hopefully) have my PDP 11/23 running (it passes CPU and memory
tests, anyway), I've been messing with my RLV11 so I can use my RL02.
For a first step, I'm trying to run the VRLBC0 diskless diagnostic to check
the controller. I checked that the address and vector switches are set to
the defaults according to he manual, and also verified them with a
The manual says the default vector address is 330, though the diagnostics
default to 160. I tried it both ways with the same result, though I should
be on 330.
I'm not actually sure what "BR LEVEL" refers to, so I left that at the
This is a PDP 11/23 with an H-9273 backplane. I have the M8186, M8067,
M8043, then the two RLV11 boards, M8013 and M8014, then an M8012.
Here's a sample run. It appears to start, but never does anything else. If
I give it a bad address it does complain, so I think I have the switches
Does anyone know what I might try next? Thanks!
