Nice work - I thought it sounded like the head wasn't moving its full travel when you described the issue. Need to get yourself the PAL adapter now - I used to have a bunch of them but I think I sold most of them. With the PAL adapter you'll be able to experience the Apple //c in colour I've just aquired an early Apple //e (thanks Danny!) - one from 1983 with a painted case like the Apple ][ and ][ europlus. Will post some photos at some stage. Chuffed to finally get one of these as I had one just like it back in 1985.
