when I get it done I will be glad to provide you with
a dump of the
root and usr partitions. I may be able to do SIMH disk images as well,
but I have been working mostly with E11.
E11 disk images in files aren't anything odd, just a straight bit-bit copy of
what would be in the parititon. (When I transfer RK05 partitions on E11 to SD
cards for use in the QSIC, I just 'dd' the file holding the partition to the
appropriate blocks on the SD card, and it comes out fine.)
Dunno about SIMH disk imaages (I know the tapes images are tweaked).

I have used SIMH to create MSCP bootable XXDP 2.5 disk images from the
RL02 XXDP 2.5 image on the net:
http://www.bitsavers.org/bits/DEC/pdp11/discimages/rl02/xxdp25.rl02.gz
I have then been able to burn those disk images straight to a CD-ROM
and have been able to boot those on a PDP-11 from a SCSI CD-ROM drive
attached to CMD CQD SCSI controllers (with the CD-ROM drive in
512-byte block mode). So the SIMH disk image is just a straight block
for block image.
