Why not make it in a way that it replaces the floppy drive inside an A500 and the CF is inserted/removed from the floppy drive slot?
That would be real neat.
That would make sense although I'm not sure about where would you put the lcd screen and buttons to change the adf. If it took a 5 1/4 bay or even better a 3 1/2 one it would be easier to fit on big box amigas or external floppy disk cases (it would be easy to exchange df0&df1 and leave the ADF-SD as external unit connected cleanly to the floppy port and leave the internal floppy disk untouched as df1).
Would it be possible that the ADF-SD "emulator" could load 2 adfs as df0 and df2 for example? It would be more comfortable for multidisk games. The games usually only access one drive simultaneously so even if the chip was not capable of handling 4 drives simultaneously perhaps it could apply some "delay" to the other drives until the current operation is finished.
