You may (or may) not also have to set the switch inside the RX drive
to RX01 (non-DMA mode) vs RX02 (DMA mode). The controller
to/from drive protocol is slightly different between the two modes,
and the drive needs to know what kind of controller it is connected to.
There is also a mode switch for PDP8 (12b) vs PDP11 (8b) mode but
that one is probably already set OK.

Does anyone know what the "005134" code
means?
I search through RT-11 docs and can't find anything on error
codes or such and I'm hoping this will help with the debugging.
That is not an error code but just the address where the CPU stopped.
By looking at the code you might be able to figure out what the
problem is. The RX11 (M7846) does not use DMA (NPR), so check
that the NPR wire on the backplane is present (pins CA1 - CB1) or
check that the RX11 module has connection by a trace on the
module between those 2 pins.
