I have a few images here and at least one (the Digital Standard Mumps
one) up on https://www.crystel.com/pdp
I can load up a few more from the beaglebone if interested.

You can use the vtserver tool under Linux to transfer a disk image created
via an emulator and have the hardware PDP write it to a disk or emulator.
It runs over the serial console.
The format of the simh (for example) disk container doesn't have all the
data a physical disk has, the low level format.
You can create an RD-image using the emulator by specifying the number of
sectors and heads, and then use XXDP to low-level format it. Then use
vtserver to transfer the simulator image.
I have done this with my 11/23+ and 11/23 several times. Even to real
physical MFM drives. Works great.
I have not found any archives for images like that though.
-Peter Indeed. I know it's cool to be modest and all
but your board is amazing.
And there will always be nut cases like me that will run RD54's and such
into the dirt, cleaning the internal filters and properly lubricating
the bearings and all :-)
As long as we're talking about it, is there anywhere that
images for it are being archived?
And, can one build an image on an emulator (like SIMH or Ersatz-11)
and use it on a real system or will I need to build all my images
on real hardware?
I have one now and hope to get my 11/93 back in operation. Would be
nice to have images for all the OSes.
