You may want to use simh (where you'll be able to
mount tapes and RL02
images) to do the installation and generate an RD32 image. Once you have
the disk image, use vtserver (note - some versions are limited to 32MB
images, but there are some that remove that limitation - check if the
struct vtcmd in vtserver.c uses 2 or 4 bytes for the block number), or
PDP11GUI (Windows only) to transfer the RD32 disk image to your PDP over a
serial port.
If you go this route, be advised, that SIMH creates RD32 disk images are not the same
size as a real RD32. This will likely cause problems when writing a SIMH created image to
a real disk (and I'm not talking about the additional issues that the trailing
metadata on disk images from the Pizzolato version of SIMH can cause - the problem I'm
describing is caused by an incorrect disk size value in SIMH).

True, I think you can get around this by making the disk in SIMH a
couple of blocks smaller.
However there is another way. Format your real RD32 with the RQDX3
formatter, then once formatted suck it into a file. Then you have an
exact replica you can mount in SIMH and load it up.
I did this with a 154mb Hitachi ESDI MCSP disk that went "bad" 30 years
ago and would not boot. Sucked it in, booted RSX11M off a virtual drive,
then mounted it. Turns out when I did a purge of old files I deleted the
RSX11M.TSK file I was using to boot because I forgot to do a /SAV /WB in
VMR to update the boot block to the new file location. Did that, system
booted, then copied it back to the "real" Hitachi disk.
Back in operation. :-)

Thank you all for the tips and pointers. I like the idea of pulling the
image off of my real drive, but how would I transfer it between the pdp and
my Linux box with Simh? It is too big for the tu58 emulator.

use pdp11gui or vtserver. They can use ODT to upload a small program to
the 11 which allows it to send or receive an image to a MCSP or
RL/RX/Whatever drive. Can be slow (top speed is 9600 or 19200 baud on an
11/23) but it does get the job done.

Hmm, not sure why yet, but I'm not able to get vtserver to work. I have
entered the bootcode manually in ODT, and I have had vtserver send it.
It looks like it loads the code and then reads one record but then hangs.
I'm wondering if my version of ODT on the CPU board needs something to be
handled differently.
Btw, the version I have found of vtserver is 2.3.1.5. I can't seem to find
anything later than that.
I am going to try PDP11GUI but I am waiting on a supported USB-RS232
adapter to arrive. The ones I have aren't supported under Windows anymore.
I should have it tomorrow.

New subject: RSX11M installation on real PDP11
Alright! I booted up RSX11M 4.2 a little bit ago on my 11/23-plus! I had
logged in to one of my Linux machines from my work laptop to run the copy,
and of course they installed Windows updates and it needed to reboot. But I
have a little more than half of the disk image copied over so I was able to
boot it up. Very exciting! I'll start the copy over a bit later in the week
when I can let it run longer. I also have a DECNA card in the machine now
so I can install DECnet and play with that uner RSX. I wish I could install
TCP/IP but I understand the hardware doesn't have the separate I/D space so
it won't work.
Thanks again for all the pointers and tips!
