I needed to dump/load disk images from my RK05's using a PDP-11/10. I
ended up writing my own facility that transfers the raw blocks over a
serial port to a modern machine. The utility is in rough shape from a user
point of view and only does RK05's, but it does use a CRC-32 to ensure the
blocks do not get transferred over a serial port. I can send the details
to anyone who is interested.

I would be interested in that. What are the memory requirements?
ISTR that was one thing about vtserver is the PDP-11 end needed a
little bit of RAM.
I've glanced at the code and wondered if there wasn't a way to bring
things down to 56K if one chose a specific disk driver and no frills,
just to expand the range of machines that are possible to use for
archiving. Since vtserver was written to place a bootable image on a
machine that had enough RAM to run UNIX, there wasn't much need to
economize, but if the purpose is archiving, one doesn't need a meg or
more just to hump a few thousand blocks of data over a serial port.
