Hi Tomlee,
You indication were more than useful. I found immediately the A0, A1 and A2 jumpers and put one in A2+A1, which gave me the ID 6 I wanted. I could have tried lot of time on this, as the SCSI IS selector on the case was connected to something at the back on the drive, while those Ax jumpers were on the middle of board of the drive. I do not know how this could have worked for the previous owner! Because of the position of the Ax jumpers, I could not installed the case ID selector on it, so it is fixed... Better than nothing!
As for the other jumper you're talking about, I did not found any clear reference to them. But the drive worked whit my IIgs and its SCSI zip drive (set to ID5).
