      And note well, if you plug an RLV11 board set into a Q/Q backplane,
      SMOKE will result. I learned this the hard way, with someone else's
      RLV11 that I was borrowing, in 1985, when an RLV11 was worth quite a lot
      of money. It took me quite awhile to pay for that with my after-school job.

      Anyway, I have several RLV12s, but all in systems. I can bring one
      to MARCH for testing or other work at some point, but it's going back
      with me. ;)
