It was suggested in private by a few people to have a hack at the
CMOS backup battery. While I fully expected the battery to be dead at
this point I did not expect it to completely brick the POST.
It turns out to be the correct fix.
With a fresh battery and the /RCLR pulled to ground for a few seconds
the first machine successfully POSTs to chevron prompt.
