Wiping with what.
The menu you
get when you hit Escape on startup has an option for
setting a floppy as 8". Mine is ROM 5.7 which I believe is the next
to last. Unless it is different than the other CP/M systems I have
FORMAT should have no hardware dependent code in it. It was the OS
that tracked and controlled what the underlying format of the
floppies were.
That's literally the only thing I could find. I can't see any place
where a DPB is defined for an 8" drive. If the DPB is wrong, FORMAT
will misbehave. I'd be utterly unsurprised if more parameters than just
cylinder count weren't wrong.
You might try examining the active DPBs for the system to see what all
it's using, and even correct it with a monitor or debugger. > I haven't had mine out in a while, but

The more I think about this, the more I think maybe the thing that
"fixed" mine was wiping the drive before trying FDISK.
You didn't show the full FDISK session, or a listing of what partitions
it thinks are there to begin with. That might help shake free thoughts
from others.
It starts out with no partitions and claims the partition table
is not a valid P112 table. The "w" command fixes that but the
table is still empty. Interestingly enough, a 64M CF in an IDE
adapter works with FDISK. but then when I try to "INIT" it under
RSX180 it prints a stream of garbage on the screen and does nothing
to the disk/CF.
Not sure how much longer I am likely to keep beating my head
against the wall.
