I still can't figure out how to format such a thing on a PC.
It's probably doable with a little chicanery. The 765 when
formatting doesn't actually care what you're putting down in the
individual sector IDAMs; for the track layout it goes by the
information in the command.
One way to accomplish such a format is to lay a track out using
smaller sectors, say 256 bytes, and specify the needed sector sizes
in the IDAMs of the sectors that most closely correspond to the
physical location of the required sectors. This is what the old IBM
XDF formatter does.
