I have used SIMH to create MSCP bootable XXDP 2.5 disk images from the
RL02 XXDP 2.5 image on the net:

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.
