I don't have any images of the 11/780 console floppy...but I DO have a VMS 
3.x console floppy.  I think diag floppies are up on ftp dot trailing-edge, too.

I DO however have images of the 11/750 diag floppies.

Try disabling all other units for the controller, and all other unused

The only person I know with an 11/730 has a currently non-functional 
one...or it lacks a drive.  One of the two...forget which so I can't 
confirm if it's a SIMH or 4.3 bug.

I'll go fiddle with it and respond with my findings.
