      TQK50 Jumper and Switch Settings

========================================================================

   The TQK50 (M7546) is a Q-bus controller for a TK50 tape (CompacTape
(tm)) drive.  It has two DIP switch sets (hardware revision level and
unit number) and one jumper set (CSR address).

========================================================================

   The hardware revision level DIP switch is set to match the module
revision level, which is stamped on the back of the module.  The eight
switches represent a binary value: open = 0, closed = 1.

      Revision             Switch
      Level            8 7 6 5 4 3 2 1
     ----------------------------------
        0              0 0 0 0 0 0 0 0
        1 (A)          0 0 0 0 0 0 0 1
        2 (B)          0 0 0 0 0 0 1 0
        3 (C)          0 0 0 0 0 0 1 1
        ...            ...


   The unit number DIP switch is similar:

      Unit                 Switch
      Number           8 7 6 5 4 3 2 1
     ----------------------------------
        0              0 0 0 0 0 0 0 0
        1              0 0 0 0 0 0 0 1
        2              0 0 0 0 0 0 1 0
        3              0 0 0 0 0 0 1 1
        ...            ...

   The VMS operating system does not use these data.

------------------------------------------------------------------------

   The jumpers set the CSR address (bits 12-2).  Jumper removed = 0,
installed = 1.
