After that worked successfully, I became disappointed
that I had to deface the floppy media with the extra holes. The
simple solution was to use a DPDT switch and flip the detection
circuits so that the RX03 drive would signal a double-sided media
what there was a single-sided index hole and the DPDT switch was
in the alternate position.
Wouldn't that approach result in the sectors being shifted with respect to the index
hole vs. the case where the conventional index sensor positions are used? I would imagine
that it's a moot point if the disks are being formatted, written and read on the same
drive, but I can imagine interoperation issues if you later punch the second jacket window
to read/write the disks on an unmodified drive.
