The RL02 images probably won't help without a real RL02. Likewise .tap
images won't help without a real TK50 or 70 tape unit.
I typically gen my own M and M+ off real RL02 packs, but this takes time
and is complicated. Thus I agree with the concept of build a RD32 image
in SIMH, install RSX to it, then copy it over to your real RD32 and get
rolling.
M 4.2 should be fine for you, however you probably want to get a FPP at
some point to more easily run FORTRAN programs. And with M you can
install Decnet 4.0 which can allow you to use the second serial port for
all sorts of fun shenannigans (I guess you could hook it to a serial
port on a Pi, then bridge via TCP to HECNet)

Hello to the group,
I have acquired some boards and a backplane for a PDP 11/23+. The disk
controller is an RQDX3 and I have a 3.5" drive that works as an RX50. I
have a greazeweasle so I am able to write RX50 images to 3.5 inch
floppies. I also have an RD32 MFM drive that also works.
Since I have an M8189 CPU board, I have a second serial port that works as
a TU58 device so I can use the tu58em emulator. I also have 512K of memory
and a DZV11. Using the TU58 emulator I have been able to get RT-11 up and
running on it.
My goal though is to try and get RSX11M (I have no FPP right now) on it,
but I am somewhat at a loss on how to get it installed. Anyone have any
suggestions on how I could do that? I have some .tap files and some RL02
images with various versions of RSX11M, but I don't know how to get them
onto my RD32 drive.
Thanks in advance for any pointers or suggestions.
And let me just say I love finally having a real PDP11!!
