[Coco] Need help (of course)

[Bill]

Dunno, the single drives work great, even though the 5 1/4" is a 35 track. Works well as drive 0. No jumpers anywhere on the drive.

And the 3 1/2" works as well. I can use it as drive 0 OR drive 1, depending where on the cable it is. No jumpers on this one, either.

But together, they BOTH light up when either is accessed with a known-good cable.

I'm stumped!!

Sounds like you might have a duff cable?  Or a drive that doesn't care?  
Two jumpers on the DS row of pins maybe?  Or an accidental bridge between traces on the 3.5" DS less drive?  Either way that would have the effect of bridging the select lines together as there aren't any isolation buffers on any drive I have ever had.
