No magic smoke so far!
I think you had written something a while back that would test that
interrupt. Was that correct, or is there another diagnostic I can use
to test that?
The 17440 wasn't a typo, it's just my misunderstanding of how the
addressing works. I'll read the actual location later today and see
what I find!

  According to the Microcomputer Interfaces
Handbook, my H9273 backplane
 should be all ABCD. 
 Yup, that was one of the first things I checked - whilst realizing that if
 it wasn't, it was too late... :-)
  Am I correct in that I shouldn't have any
problem using the RLV11 in
 that backplane? 
 Not that I am aware of.
