I was making some RX01 floppies for a needy forum member and decided to photograph my process for turning double sided 8" floppies into "flippy" RX01/RX02 media. "Flippy" because RX01/RX02 were only written on one side, and with approriate modification can be used on both sides.
RX01/RX02 are single sided disks. 8" single and double sided disks have the sector holes through the jacket clocked differently. For some reason, I seem to come across much more double sided media than single sided media. Here is my process for making the double sided media usable in the RX01/RX02 drive....
These are the tools: http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18055 . The most important tool is an old jacket from an RX01 floppy. It will be used as a template. The media must be removed. It can be done by using a razor blade to slit open the top edge of the jacket. The other tools are a fine point sharpie, a hand hole punch, and a business card.
Use the jacket as a template. See here: http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18056 that the sector holes are in different places. The disk on top is a double sided disk, and the jacket in the back is from a single sided disk. Lay the jacket over the double sided disk and mark : http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18057 the front: http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18059 and the back: http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18058 . The template needs to be flipped on both sided of the double sided disk to make the two marks per side. You'll be punching four new holes in total.
Slide the business card in the spindle hole under where the new holes need to be punched. The card protects the media surface from the hole punch. http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18060 . Then punch it, used the sleeve the disk came with to protect the media from being touched through the head access hole in the jacket: http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18061 . Then punch the other side.
When you're done http://www.vintage-computer.com/vcforum/album.php?albumid=229&attachmentid=18062 you have a flippy single sided disk. It can be formatted as RX01 in a PC with PUTR, in a DSD440, or by other means (not involving a real RX01 drive.)
