  Thoughts? 
What Dave said, but a few reminders.

First, make sure that the drive is jumpered for high density by default,
since the density select line won't be active on the 8" connector. 
Or the 5.25 connector either!

...
 Most 1.2MB 5.25" drives are jumpered to provide
DISK CHANGED/  status on
pin 34; I believe the Disk 1 requires READY/, so change your jumpers
accordingly. 
The READY/ can be jumpered for 5.25 floppy use as it's not always there.
The disk 1A has a jumper for this, if the disk1 does not then a red wire
jumper on the back of the board will do this.
