If Ian can archive good images using Kyroflux and the rest of us can 
convert those images to other formats then we all win!

Ian, what do you need to go forward? If you have a list of floppies you 
either want images of or the physical disk I will help where I can. Much 
like the archiving of the 9010 tapes, this needs to be done sooner 
rather than later as floppies are failing due to age...
