Dilog DQ614 diagnostics program first tests

Hello everybody and Happy New Year (if applicable). I did the first tests with the DQ614P.SAV program and my Dilog DQ614 MFM controller board. This board simulates up to four RL01/02 units in one PDP-11 using one or two MFM hard disks. I am using: * One PDP-11/23 PLUS with 128 Kwords of memory * One PC connected to the second SLU simulating one TU58 double unit (thanks, Will Kranz !) * One Dilog DQ614 Revision S * One Quantum MFM Hard Disk Q540 (Aka. RD52-A) * RT-11 v.4 Environment tips: * I have configured the Dilog board to work under one PDP-11/23 PLUS like the manual suggest. * I did the probes simulating one up to four emulated RL02/01 disks. * I assume the vector addresses of the unit is 174400 and 160. The software used is the DQ614P.SAV diagnostics program Revision 0, and one DL.SYS driver that came with the DQ614P program. Well, the program starts ok. There is no apparently problem with the OS environment. It works with its DL.SYS module, with the own DL.SYS module of the RT11 V.4, and without it too. The program startup and asks me if I'm working with a C.R.T (I assume it speaks about a terminal). Later the program asks me about the access vector for the controller. By default it uses 174400 and 160 values. I assume them too. The next step is to select one MFM hard disk. My disk is the 73, one Quantum Q540. Inmediately, the program permits me to select how much DL disks I want to emulate. I can emulate two RL02 and two RL01. The program asks me: "Are you sure ?". My answer is yes. The process begins... and some seconds later, the program send me a message telling: "UNEXPECTED RESPONSE IN ADDRESS 00000160 (sometimes is the address 00000000). I've tried to change the cable selection, the address selection, etc... In this case, the message tells me that the unit can't be accessed. Like a final indication, the Q540 hard disk have 5 jumpers named DS1, DS2, DS3, DS4 and ^. Actually is selected the DS1. What is wrong ? I suspect that the program must be the same revision than the board (Revision "O" the program, revision "S" the board). If somebody can supply it to me, I'll agree a lot. Any other suggestion about the vector address, etc, are welcome. Thanks and Greetings Sergio
