Clarification for anyone coming to this thread late (like Knight Rider, who thankfully asked all the right questions by email before I sent his board):
1) The board cannot be used as a "live" floppy controller for Raspberry Pi to read disks into an emulator on the fly
2) The board cannot write disks, it can only read them
Result of which - I still have one board left if anyone wants it!
As it stands the physical board is wired up to be able to emulate a floppy to a host device, and to be able to write to floppy disks.
It's just my primary focus has been in reading and archive data from disks, so all the software I've written so far is read only.
I like the idea of it also being a floppy emulator, and I know people have done this exact use case with Raspberry Pi add-on circuits like mine.
Admittedly floppy emulation is probably more useful that actually writing to ageing floppies.
My Beeb is currently not working, but my floppy drives are, hence the focus of archiving.
Here's an example of a project for the Raspberry Pi 1 from somebody in Canada which supports both read and write, and one where I drew some of my initial inspiration for my PCB from (and to know it was possible). They have targetted the TRS-80 using DMK image files. This project could be made to work with my PCB with a bit of tweaking.
