Hi,
I recently had to replace defective floppy drive to our VRS1 controller there are few tricks I would like to share with others too:
1. IBM-PC compatible floppy drive wont work with VRS1
2. SEF has original units cost is around 400-500 Eur
3. Floppy drives(DD or HD) that work with Commodore Amigas will fit :ylsuper:
Amiga floppy drives are unfortunately a bit rare these days :(. But should be available in some Amiga concentrated internet shops. It is also possible to "modify" some PC floppy drives to work with Amiga/VRS1 http://www.carrott.org/amiga/floppy.html About floppies at least controller version 1.14 and older don't work with HD(1.44mb) floppies but they need older DD(720kb) floppies. I guess if you find a place that sells Amiga compatible floppy drives they sell DD floppies too.
