You could boot a packaged Linux that doesn't need installation but runs
directly from the boot device. I haven't done this but I know they are out
there and easy to use.
SimH complex and lots of setup? Not my experience. The documentation may be
sparse in places, as I found when configuring a PDP-10 setup, but the PDP-11
setups are well documented.
SCSI controller, that's beside the point. I assume it looks to the PDP-11 as
an MSCP controller, right? It would have to be, else you'd have no chance of
running a standard OS. If so, you'd just tell SIMH to configure an MSCP
controller with a disk of size matching what you have.
When you said "won't write a disk image to a real RX50" do you mean an RX50
drive, or an RX50 floppy in a plain PC 5.25 inch drive? I don't know about the
former, but the latter has long worked for me. I haven't used Windows for
stuff like that in ages, and don't want to use it if I can avoid it, but my
RSTSFLX 2.6 can be build for DOS (using DJGPP). I don't have an executable of
that version handy but could probably create one. That doesn't create from
images, though; it manipulates RSTS file systems. A simple program to copy an
image, along the lines of the rx50.py I mentioned, would not be hard to make.
