A bit late on this one...
When this conversation came up, I forwarded the conversation to Andy Taylor (andytuk@gmail.com), of www.retrocomputers.eu, and a member of the Peterborough LUG.
He indicated that he was more than willing to assist with the problem of getting data of Acorn (or was it Amiga?, I forget) floppies and has some experience of such things. Obviously the initial query has been resolved but I am sure his offer to help with anything relating to old kit stands (and he's always after donations of obsolete kit of historical value).
Anyway, I asked him whether he was OK for me to post his details here, my message hit his spam folder, and he's only just seen it to give me the OK.
I've CC'd Andy on this but note that he is not currently an ALUG subscriber so won't see replies unless he is CC'd (and if he replies they won't reach the list unless he thinks to subscribe when he reads this).
