Doesn't that Flipper like the other two Catweasels read and write every format that is in their (long) list ?? You only need to connect a pc discdrive. Being an ex-C64 freak it could be hard to find old 5,25" drives ...
About that Zorro and PCI connector of the Flipper, don't forget the clockport connector for the A1200 or every card with clockport connector(s) !!!
