Hm.. I might be able to convince a german friend to translate ;)
At any rate, I imagine watching the servo lines on the 6522 is a good idea.
You can calibrate just like the mech does by counting to 0 as it slams the
head stop and keeping track from there.
I dont know, however, what to do when the drive doesnt need to slam the stop
after initial power-up. :(
