"PRINT INP(&CAFE)" does print current disk selected number.
=== TODO DONE : A advanced dsk drive ===
With true write enableDone on r004, writing I added also a second Drive in dsk order to copy easily files, and digest of strange from one disk to another. Irregular sector size ok. You just have to select Drive A or B from OSD before selecting another dsk formatfile. Write is done directly on sdcard dsk file, so you can save games, and eject possible to write texts... You can now change dsk facedisk without reset. Perhaps a key to switch face quicklyAnd then play games using several disks.
