I do have an RD54 image that can be used with mfm_write. Search in page for RD54
http://www.pdp8online.com/mfm/status.shtml
Ok. Hm. So the command would be ./mfm_write --emulation RD54_A -d3?
This is possibly better than nothing: I could use this to put some sort
of format on the drive, then try letting xxdp reformat it. Right now I'm
getting this:
DR>START
CHANGE HW (L) ? Y
# UNITS (D) ? 1
UNIT 0
Enter controller IP Address (O) 172150 ?
What unit do you want to format [0-255] (D) 0 ?
Would you like to revector a single LBN only [Y/N] (L) N ?
Do you want to use the "AUTOFORMAT" Mode [Y/N] (L) Y ?
Enter unit serial number [1-32000] (D) 12345 ?

(Oddly enough the old controller doesn't display the progress. I really
think it's just talking to the RQDX3 and that is calling the shots as
the later ROMs do tell you how far it is and what it's doing which is nice)
