An other reason to go for RX02 is that with RX02
you can also
read RX01 formatted floppies. The RX02 drive has internally
a switch to act as an RX01. It is ovbious that you can not
read RX02 formatted floppies with the RX01 drive.
The switch -- if you're referring to the small 2-position DIP switch --
is only used if you want to connect an RX02 drive unit to an RX11
controller, as if it were an RX01 drive unit (it's also used to set how
the RX02 behaves for an RX8 controller). You don't need to change it to
read RX01-format floppies in the RX02 connected to an RX211. If you do
change it, the RX02 won't work properly with the RX211 any more!
