So you added a "Viking", if I see right.  What sort of device is that?

If it's an MSCP controller, it would go into the UDA50 floating CSR position.  DHV11 and TMSCP rank later than UDA50 in the floating CSR order, so if you added a MSCP controller without adjusting the CSR address switches of those two cards, they would not be correctly recognized as I discussed in my earlier mail today.  The order of the cards in the chassis does not affect that; device identification in Unibus and Qbus has no connection to physical card position.
