Changes
/* TODO : arnoldemu's testbench fdctest */
Contains the DFC "SK bit" test.
Have also to fix theses "Bad Command" response from dsk (it seems that when not reaching a track, you send back the current track, not a "Bad Command" signal). Test : 30YMD demo, "disk change" message not running correctly, "another disk inserted" is not detected in this demo.
=== TODO : github migration ===
