I forgot to mention one item. Since I had VERY few

media with the index hole offset that extra 1/2" from the Single Sided
index hole - and I have many RX02 compatible floppy media which
are Single Sided with the index hole in the wrong place for being a
Double Sided media - I added a DPDT switch to the sense circuit
of the DSD 880/30 drive. In the normal position, the Single Sided
floppy media are detected as Single Sided floppy media. In the
opposite position, a Single Sided floppy media is detected as Double
Sided and the DSD 880/30 is then able to read / write both sides
of the floppy media. Since the DSD 880/30 is also able to perform
a LLF (Low Level Format), I am able to use all of the RX02 media
as Double Sided WITHOUT the inconvenience of having to punch
the extra index hole.
My drives are configured to take either index signal--so it doesn't
matter if the media is coded as SS or DS. Many floppy drives can do this.
