I've had a look at the floppy formats supported by my conversion system,
which btw originates in the UK. I havnt come across BBC formats in the
servicebureay, but according to the software BBC is found in quite some
flavours, reaching from single-side single-density 5.25" to DSDD 3.5"
Before you spend a lot of time playing around with things, it would be good
to know the discs physicals and logicals.
I would be happy to help out, so if you send me one or two discs, I can tell
you the characteristics. From there, you can start tinkering, or e.g. find a
Microsolutions Compaticard IV card. If you have only relatively few discs, I
could convert them for you for P & P and a pint or two.
