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.
