Wild guess. Pin 34 changed its definition at some point (IIRC it used to 
be Rdy/, it bacame disk_change/). Maybe that's your problem.

The thing that really annoys me about the Teac documentation is that the 
jumpers are not explained in the service manual (and on later drives with 
one big ASIC, you can't really work them out). OK, they're probably in 
the OEM manaul, or something, but if all you have is the service manual, 
that's not a lot of help...
