The following files are intended to help use a DILOG DQ614 controller on a
PDP-11.  A DQ614 is a dual-height Q-Bus controller capable of handling one or
two physical ST412-compatible hard drives, emulating an RLV12 with one, two,
three, or four RL01 or RL02 drives.

The  DQ614_layout.ps  file is a drawing of the board showing jumper positions
etc (PostScript file).  Note the PROM at U38.  On my DQ614, this was part no.
91578A, which set the controller CSR address to some alternative address.  The
standard PROM, part no. 91265D, sets the standard address of 17774400, with
vector at 160.

The  DQ614.ps  file is a (retyped) copy of the tables showing how to set the
jumpers etc on the card (PostScript file).  Setup consists of:

  1. ensure all the switches in Table 2.1 are properly set
  2. ensure all jumpers listed in Table 2.2 are properly set
  3. verify the controller is firmly seated in the backplane
  4. verify the cables are properly installed in controller and drive(s)
  5. apply power to the drive(s), computer, and terminal
  6. verify that the green diagnostic LED on the edge of the controller
     board lights up

Then boot the system (the on-board bootstrap handles DY and DL devices), and
run the formatter as required.  It's menu-driven, and fairly self-explanatory. 
To paraphrase the manual, to format, specify the drive type, the emulation
(RL01/RL02), number of alternate cylinders (spares), and the program does the
rest.  To run diagnostics, specify the test and the unit.

The file  DQ614P.SAV  is a dump of the diagnostic/formatter program from the
DILOG disk.  This was a bootable RX02 with RT-11 V5.04 and the SJ monitor.  As
far as I know, all that is required is the formatter program itself, but YMMV so
I've included the DL.SYS driver from the floppy.  Both files were copied to a
Unix system using Kermit-11.  This is a directory listing of the original disk:
