The attached ZIP archive has been updated with my latest status of the Forth ROM disassembly.
The files should now be very, very close to being assembled, e.g. by the A09 assembler.
It may be easier to recreate the ROM for different system ROM versions this way, as one only has to change the list of entry points.
I believe that there are at least 250 unused bytes at the end of the ROM as well as some interspersed unused bytes which would allow adding one or two extra words. e.g. for talking to one of the the serial interfaces.
As this flow was rather exhausting, I will pause here and continue in a few days or weeks.
