Possibly due to the battery damage, that bastard, although absolutely ok upon visual inspection, must have lost most of its resistance so that Gary became unable to pull /VPA down.
For a first test, I cut R1000 off, measured the resistance of /VPA again (2.7k this time) and gave it a go. A few seconds later (with my fingers crossed) I finally heard that beatiful "klick-klick-klick" noise from the floppy. It never sounded better... :-D

Battery damage can be subtle, pleased you found the fault.
