I found

But I couldn't find the tools to use these files to create microcode

There's a small chance that the tools.tar.gz link on
http://www.ak6dn.com/PDP-11/M9312/ has these, but that's for a different

http://filedump.theglitchworks.net/software/vintage/dec/roms/bdv11_upgrade/
has a number of ROM images. Don't know if they are the ones you want. What
are the XX-XXXXX-XX numbers on the PROMs you are looking for?
