If this helps anyone:
After 4 years I finally fixed it, it was a bad 6525a chip in the disk drive (the tri port interface). The cartridge seemed OK, I could write to port A and get the same result back. However, it seemed no signal from the drive would be travelling back to the cartridge, in fact the faulty 6525a didn't do anything at all. So I spent 40 $ on eBay to get a replacement. Was it worth it? Maybe the drive works now for a few months before it breaks again :-/
