As always, things are not that easy :-) I'd have to leave at least 3 of 6 lines in their original use (drive selection) so other microdrives don't get totally confused. The other three lines are just one output and two data lines (both seem to change their direction at the same time, according to that output). And I don't know wether the data lines can be bit-banged at all. Even if I construct something useful from those 3 lines - which would of course involve more that just level-shifting - there is still risk to confuse the microdrive portion of the OS.
