need a bit of help debugging the floppy controller. Thus far I've

I wonder if you've got a DMA problem. When the 765 is formatting, it
doesn't care too awfully much about the formatting data that's being
passed along--it'll stick anything in the address headers. But you
mentioned that it does perform the formatting, which means that the
765 program-mode I/O is working.
Have you looked at your Otrona-formatted floppies with a utility that
just does READ ID operations to figure out what's being written?
Anadisk might be a good start. Something like the TE utility for the
CopyIIPC option board would be another.
Just a thought...
