I found another box so I’ve got 20 ‘new’ ones now. I’ll try all of the above methods and see where it gets me. Pity I don’t have any spare jackets but my plan was to attempt to get the CPT to boot and since the original boot disk has damaged sectors 0-3 and the previous owner didn’t make a copy I’m a bit stuck anyway.
It was good to be able to see actual documents on the data disks with ANADISK though, cheers Chuck :)
