My diagnostic plan is as follows:
1. Remove the RD52 hard drive. Avoid any potential conflict with the RX50 drives.
2. Check the voltage supplies to the drive cables.
3. Reinstall link W23 as I found it originally.
4. Just seen the LED on the RQDX3... This LED should illuminate on a RESET and should extinguish if the self test is OK.
5. I have spare RX50 drives - so I could replace the RX50 drive for another.
6. I would then replace the RQDX3 with an RQDX1.
Hopefully, one of these actions should result in an operational system.
In the meantime, I will read up further on QBUS bus priority slot allocation...
