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