Trying to figure out a "new" logic board in an otherwise proven SE/30 computer.

Known good ROM SIMM

Known good all RAM modules

Known good floppy & hard disk drives (known good Disk Tools or system software)

Starts with no chime but with a good image of the "happy Mac" on the CRT, goes to the "Welcome to Macintosh" screen but doesn't go any further. Just after the welcome screen appears either the floppy or the hard drive quits reading.

The "Repair Macintosh SE/30" site doesn't have this particular problem. I hope its just dust somewhere.
